Buh-Bye, Blair Waldorf! Leighton Meester Has Platinum Blonde Hair

Sydney Sweeney turned heads when she showed up to the Vanity Fair Oscars afterparty in a mesmerizing pink Miu Miu dress with a keyhole detail and mermaid style skirt.

To achieve that glossy, healthy hair, hairstylist Glen Oropeza used a couple drops from Kératase's new Gloss Absolu Glaze Drops, followed by the Kérastase L'Incroyable Blow Dry Hair Lotion. A hairdryer and round brush (plus a touch of hairspray) gave Syd's hair that bouncy finish.

One of my favorite tricks for my own straight hair is to apply a leave-in conditioner, like the Christophe Robin Hydrating Leave-In Cream, to my dry hair and let it soak up all that moisture. It makes it shinier, smoother, and healthier than ever!

This isn't the first time recently one of Sydney's looks started some serious online buzz. After a post of Sydney's new role as boxer Christy Martin received some hate comments, the actress clapped back with a video of her training for the movie.

“Well the cat’s out of the bag thanks to some paps in bushes so here’s a little BTS from my film I’m working on right now,” Sydney Sweeney said in an Instagram post. “Over the past few months, I’ve been immersed in training to bring to life the story of an incredible woman — a true champion who fought battles both inside and outside the ring. Her journey is a testament to resilience, strength, and hope, and I’m honored to step into her shoes to share her powerful story with you all. more to come soon :)."

“I grappled and did kickboxing from 12-19 years old," Sydney also told Deadline. "I’ve been itching to get back into the ring, train, and transform my body. Christy’s story isn’t a light one, it’s physically and emotionally demanding, there’s a lot of weight to carry. But I love challenging myself.”

1. Deep Side Parts

Coming in at #1 on our "outdated" list are deep side parts. They used to something we admired on everyone from Amy Winehouse to Katy Perry, but now they remind us of the questionable choices we made in our early 20s.

2. Space Buns

Princess Leia may look great wearing her space buns in the Star Wars franchise, but we think you shouldn't bring them into 2025. The last time someone on our team wore them was between 2018 or 2019, so that should say a lot.

We don't say this often, but let's wear hairstyles that don't revert us back to our grade school days.

3. Side Braid

Unless you're trying to relive your childhood days or want to mimic Blake Lively's character in It Ends With Us, this outdated hairstyle shouldn't be on your list of favorite looks to wear. There's other braided styles you can wear that are way more stylish anyway!

4. Super Visible Highlights

Whether you're getting microlinks or a sew-in, wearing super visible highlights in 2025 is truly outdated. It's one thing to switch up your style, but it's another to let the world know how much you love a good contrast by letting your hair scream it from the mountaintops.

Keep your color of choice seamless this year if you decide to get a color service.

5. '60s Up-Do

There's a time and place for everything, including updos that resemble what was popular during the '60s. If you must wear this style, go for a more modern take that doesn't feel as stiff. You might want to update your bangs too.

6. Wand Curls

When's the last time you heard someone mention this once popular style? Chances are you haven't because it's a reminder of how long it took to achieve overly done curls. Depending on the size you wanted, you could spend anywhere from 45 minutes to over an hour on this style. Oh, and it was mandatory to wear the accompanying glove that came with the 'wand' or else you risked burning your fingers!

No thank you!

7. Barbie Bleach

Remember when it was a cardinal sin to show up to the beach without "effortlessly wavy" hair? It seems more people are moving away from that and embracing 'messy' buns and the beauty of textured hair. It's one thing if you hair naturally looks like this, but it's another if you try to make your hair conform to this style just because it's "on trend."

Newsflash: you don't have to force your hair to do something it doesn't want to! (And not everyone has to look like Serena van der Woodsen!)

8. Millennial Pouf

Oof, how can we forget the millennial pouf? This was one of our go-to hairstyles that we swore we'd always wear. Little did we know how much we'd avoid it once we graduated from college.

It's not the most annoying style, but we're throwing this one in the "outdated" bag so we can't even pretend we're going to start wearing it again.

Sadie Sink will have a "significant" role in 'Spider-Man 4.'

Tom Holland confirmed that Spider-Man 4 is set to start filming in the summer of 2025, and Deadline reports that Sadie's role is "significant." Brit + Co reached out to Sony and Sadie Sink's reps for comment.

While we don't have any official news on the specifics of Sadie's character, considering the movie comes a couple of months after 2026's Avengers: Doomsday, I think there are a few characters Sadie would knock out of the park.

Is Sadie Sink playing Jean Grey?

With Sadie Sink's red hair, she would make a perfect variant for Zendaya's MJ (who is, herself, a version of Mary Jane from the comics). But with her sunny disposition and confidence, I could totally see her as Gwen Stacy too. My lead theory surrounding Avengers: Doomsday is that the characters we know so well will wind up in another universe — and could finally bring the X-Men into the MCU.

Even before Sadie's casting was confirmed, the leading rumor was that she'd join the MCU as Jean Grey/Phoenix, a role held by Famke Janssen and Sophie Turner in previous X-Men adaptations. And this is the role I hope we see her in!

Spider-Man fans will remember that No Way Home ended by erasing Peter Parker's existence from the world...but if Peter meets characters from another world (ahem, Jean), or if all our favorite heroes wind up in another world, the spell shouldn't affect them. And fighting to get back home is exactly the kind of theme I'd love to see in Spider-Man 4.
