What You Need to Know About Kate Middleton’s Pregnancy Condition, Hyperemesis Gravidarum

Munn shared with TODAYthat she didn't initially plan to show her scars on the set. The campaign was focused on her recovery post-breast cancer diagnosis, but the makeup artist had a hard time covering up the scars throughout the shoot. She explained that she took a look in the mirror and thought, "I’m done being insecure about my scars." From there, she took the idea to show them off to the SKIMS team — and the rest is history.

And while she was scared to be so vulnerable on camera, this was ultimately a really empowering move for Munn. She elaborated that there are "so many women that have these same scars" who feel just as insecure as she did about them — and she really hopes those women see this ad. "Skims is so iconic and associated with beauty and sex appeal, and cancer really doesn't have that same connotation," she said. "So I just really hope that other women who have gone through my same path feel a little better after seeing it."

The star also took to Instagram to give a behind-the-scenes explanation of her experience. She reiterated that she was "done being insecure" about her scars. "Every mark life has left behind on my body is proof of how hard I fought," she wrote. "I hope other women who have been self-conscious about their scars see these photos and feel all the love I’m sending."

She also shared that SKIMS will donate 10% of their bra sales (except bralettes) to Susan G. Komen® — a charity dedicated to finding a cure for breast cancer — from October 23-31 in stores and online. "It’s really meaningful to be part of an initiative that supports research and helps countless individuals impacted by breast cancer," she said.

All of this comes on the heels of Munn's announcement earlier this year that she was diagnosed with breast cancer. She revealed the diagnosis came after recently tested negatively for well-known breast cancer genes and had normal results from her annual mammogram — but her doctor to check her Breast Cancer Risk Assessment Score. The test showed Munn had a 37% risk of breast cancer, so she pushed for more answers that eventually lead to her diagnosis.

Since then, Munn shared with PEOPLE that she had 4 surgeries in 10 months and underwent medically-induced menopause — all the while juggling being a new mom with husband John Mulaney. She shared, "I'm lucky. We caught it with enough time that I had options. I want the same for any woman who might have to face this one day."

After that March announcement, it's clear Munn is dedicated to raising awareness for women's health — and particularly their options. While chatting about the SKIMS campaign, Munn told TODAY, "You've got to go your doctor and you inundate them with information and you don't stop until they give you the test you need."

Despite the fact One Tree Hill might not have been considered the golden child at the time, the series has garnered a cult following since its on-air days, drawing fans to Wilmington, North Carolina for its anniversary celebration, and nearly breaking the internet when news of a sequel series leaked online.

"It's very, very early development," Burton says. "And so what has been really cool for us? And when I say us, I mean the entire cast, like everybody and our old crew, they're all really proud of the work that we did back then too. And so to see the public support this little show we made 20 years later, that's so special and it's so rare. And I love that, even though that news was leaked, Netflix gets to see that public outpouring of support. That's cool. So, fingers crossed we'll make it to the next step."

Burton was in her twenties for the majority of OTH, and while she (alongside other female cast members of the show) have since vocalized the mistreatment they experienced from showrunner Mark Schwahn, the challenges of her twenties don't overshadow the accomplishments.

"I was not afraid to say difficult things in my twenties," she says. "And what I can tell other people in their twenties is that the long game will pay off. If you say the difficult thing and you say the truth, and you don't mask and you don't make up an alternative narrative, people will eventually realize that you were right."

Although the people pleaser in all of us might not want to rock the boat, she praises young people who refuse to accept toxicity: "We definitely have a feistier generation coming up than what I grew up in."

With her fiery attitude and sharp sense of humor, I have no problem believing Burton was one of the feistiest women of her generation, and she now finds herself advocating for a new phase in her own life: perimenopause. The actress is currently partnering with OLLY for their new Mellow Menopause supplements, bringing awareness to a conversation that should have been happening all along.

Burton never really had a menstrual cycle until she started birth control, which messed with her hormones and led to a Xanax prescription she never needed. And as she aged, she moved from having pain during her period to having it during ovulation. "I felt like there was something really wrong with me because no one had explained that could happen," she says. "So the more we can throw out what the symptoms are, I think the calmer people will be in their exploration of their own bodies."

Knowledge and education are power, and Burton firmly believes the more you understand your body, your hormones, and your emotions, the safer you'll feel. But that's only one silver lining she's found.

"I've talked about the feminine rage that I feel like I've earned," she says. "That Kesha song 'Joyride' came out this summer. She says, 'I've earned the right to be like this.' And I was like, 'Yeah, of course.' I think we spend our twenties experimenting. We spend our thirties kind of, like, establishing our careers and what our goals are. And then our forties are about knowing who we are and owning it. And if biology wants to come out swinging, I think we're in a place where we can control that and we can handle it."

That isn't to say perimenopause hasn't come without its unexpected moments, like having to convince others she really was experiencing perimenopause, despite being "too young." "The more research I did, and then in talking to my doctor, my instinct was right," she reveals. "I was beginning the [menopause] journey, and rather than try to hide it or treat it like a deficit, I get to own it. Now I get to treat it and I get to help other women navigate it. And that feels so much better when you're going through a bad thing, but you know that you're helping someone else through it. It doesn't feel as scary."

But while it's important to be vocal about our experiences, I also can't help but point out how it feels like men never have to talk about aging — they just get to do it and no one bats an eye. "Yeah, I think it's important to act like a man," Burton jokes. She remembers when her husband (actor Jeffrey Dean Morgan) embraced his natural gray hair, no one in the industry considered him too old for Hollywood.

"In fact, people thought he was hotter," she says. "So I wanted to act like a man in that journey [and embrace my own gray hair]. And so the different reaction I had was a little bit startling, but also made me laugh...I want to treat this chapter of my life as my expertise chapter. I know what I'm doing. I've been training for 20 years, 25, it's been a lot and I wanted to acknowledge that I know what I'm doing and when I talk about my body, I want to know exactly what I'm talking about."

And part of that expertise is knowing herself inside and out. On the days Burton doesn't feel like herself, whether because of hormones or mental health, she emphasizes how important it is to actually communicate those feelings. "It has been vital for me to communicate, not just with my husband, but with my teenage son," she says. "I want him to grow up to be the kind of man that's supportive of the women in his workplace and the women in his life. You know, we all talk about how we need to educate our daughters, but we also need to educate our sons."

And looking back on her own teenage years, Burton reveals her experience with perimenopause has actually reinforced the values she identified during that period in her life. "I think being a teenager and seeing these people who were gods [in the industry], seeing how insecure and unhappy some of them were really tipped me off right away," she says. "Success is being okay in your little bubble, being okay in your bedroom at night when you're alone by yourself. And so my goals have always kind of centered on, 'Do I feel okay when I'm all by myself?' and menopause is one of those things that can rattle that safety for people."

"It's about knowing who you are so much that no one else can take it away from you," she continues. "And whether it's your work or a sh—ty boyfriend or whatever, you have to know yourself so well that no one can take it away, and menopause can mess with that sometimes. And I'm gonna fight like hell to keep who I am."

When did speculations about 'The Simple Life' reboot begin?

Peacock first shared a video clip on Instagram that hinted something special involving Paris Hilton and Nicole Richie is coming in May. A nostalgic TV set with a black and white screen can be seen while our favorite duo's voices can be hearing saying, "Sanasa, Sanasa."

Peacock captioned the post, "New Era. Same Besties. Coming soon to Peacock," and fans could barely contain their excitement. Even celebs like Naomi Campbell and Katy Perry commented on these hot vibes.

Then Paris Hilton took to her own Instagram to share more about what fans could expect. She said, "As some of you may know, we are doing a reunion special to celebrate 20 years of our show The Simple Life and it's been so much fun."

Actress Selma Blair shared how much she's looking forward to this by commenting that she's "living for this."

So are we!

What was 'The Simple Life' about?

The Simple Life showed Paris Hilton and Nicole Richie as they basically traded their wealthy lifestyles for 'everyday' living. Cameras followed them from fast food jobs to dealing with getting out of sticky situations they'd supposedly never experienced. Needless to say, it was hilarious, iconic, and instant reality TV gold.

How long was 'The Simple Life' on air?

The Simple Life was on air from 2003 to 2007 with five successful seasons. It seemed like it wasn't going to be hit at first, but it defied expectations. By how much you ask?

According to reporting from The Cut, somewhere around 13 million viewers tuned in to watch Paris Hilton and Nicole Richie's oddball take on daily life. That's a pretty huge deal if you ask us!

When will 'Paris & Nicole: The Encore' debut?

Paris & Nicole: The Encore will premiere on Peacock December 12! The two were previously seen at a Sonic drive-thru yesterday so it can be assumed filming is underway (via People)!

Sporting partial Sonic uniforms, Paris Hilton and Nicole Richie added accent pieces that match their signature flairs. Paris wore a pair of reflective sunglasses, silver sequin heels, and added a pink flip phone to front of her blue apron. Nicole wore gold hoops and a pair of slingback pumps alongside her hotdog mascot costume. That's hot (dog).

How does Paris Hilton and Nicole Richie feel about reuniting for a reunion special?

Paris Hilton has expressed how much she loves to be sharing the screen with Nicole Richie again. "I'm so excited to be doing this with Nicole on Peacock. Nicole has been my best friend since we're 2 years old, every memory that I have is with her," (via E! News).

Nicole also posted a few throwback moments from The Simple Life on her Instagram, but the most notable one is the video mashup of them singing "Sanasa, Sanasa" over and over. "20 years ago, not only did we become television stars… we became song writers. Happy Anniversary Sill @parishilton#TheSimpleLife#sannnasaaaaa" she wrote in the caption.

What have Paris and Nicole said about their reunion special?

Paris Hilton and Nicole Richie sat down with W Magazine to let the world know the Paris & Nicole: The Encore show is on its way! Not only that, but fans can expect to see an Opera version of the show they fell in love with two decades ago. Paris said, "The idea of the opera was unexpected" while Nicole chimed in with, "What people need, even though they don't know it yet, is for 'Sanasa' to be an opera.'"

The two besties came up with the idea via a series of texts that started off as ideas between them. Nicole said everything "came up organically" for the two and we can only imagine the memories this brought up for them. OG influencer Paris even talked about how The Simple Life was an "important show in pop culture history" and we couldn't agree more!

Nicole truly wants people to enjoy themselves while watching Paris & Nicole: The Encore and "find the same joy" she had while filming it. According to Paris, she feels what they have is "magic" because "there's just so much history behind it."

It's not every day that you can get to have fun with your best friend while coming up with long-lasting memories that contribute to pop culture, but Paris and Nicole have always danced to the beat of their own drums. Now we'll get to see them in action again!
