I’m Ready for My Genetic Closeup

"I paid for some of the upgrades and the first thing that came up after I found out that I was part neanderthal, was this: Identical twin," she said in a video clip, showing off her family tree with a little circle next to her initials. "That has to be a joke, right?"

The Cravings cookbook author, 37, explained to followers that she wrote to the company, texted her doctor and even reached out to her twin, to no avail. Following the life-altering news, Teigen called her father to find out the truth.

"I'm literally saying, 'Dad, hey, did you see me come out of mom's vagina and were there two of me?' Teigen recalled. "He starts laughing, saying 'No, I was there, there are not two of you!' I was like, 'Are you sure you were there?' "

She then made another call to her sister, who gasped after Teigen directly asked if she had an identical twin.

"At this point, I'm making excuses for my whole life. I'm like, 'This is why I'm so codependent, because my twin was ripped away from me! This is why I always felt something missing and this is why I have addition issues,'" Teigen said. "...I'm like, literally, 'Holy f*ck!'"

But Teigen's sister reminded her of a PBS show that she participated in, Finding Your Roots, which features celebrities diving into their ancestral histories. Though Teigen's episode was never finished, she did complete a DNA test and put it under a pseudonym to protect her identity.

As it turns out, Teigen’s identical 23andMe twin was (much to her surprise) herself, as her previous genetic contribution was already registered in the service’s database.

"My identical twin was myself!" Teigen said.

Biostrap Total Health Set $250
This wristband and "shoepod" tracks your heart rate, oxygen saturation, respiratory rate and sleep, plus gives you detailed information about your workouts. You can even create your own library of custom workouts.

Body Scans and Tests

Genetic testing, whole body MRIs and 3D scanning are just some of the innovations that go beyond your annual physical:

23andMe $199

This home-based saliva testing kit is all you need to get the deets on your DNA. Simply spit in a tube and in a few weeks you'll get reports letting you know about your likelihood for certain health conditions. According to the company, 76 percent reported making healthier choices after using the product.

Vo2 Max up to $250, depending on provider

VO2 max tests the amount of oxygen you use during your workouts, which is known to be the best indicator of how fit you are, how fast your metabolism is and your overall cardiovascular fitness. You'll find this test at some gyms and holistic health clinics (Google VO2 max testing near me). How does it work? You'll wear a mask and heart rate monitor hooked up to a treadmill or stationary bike that collects and measures the volume of oxygen you inhale and exhale.

DEXA Scan $75 for initial assessment, $50 for subsequent

A DEXA scan is a diagnostic test similar to an X-ray that your doc can use to measure your bone density and whether you're at higher risk for fractures (it's often used to diagnose osteoporosis). But it also can measure your lean muscle mass and body composition to help inform your workouts. Research from the University of Oxfordshows that butt, hip, and thigh fat is healthy and can actually lower your risk of heart disease and Type 2 diabetes while extra weight around your waist can lead to obesity, which means it can be good to know where your fat sits in your body.

Fit3D Proscanner Cost varies by location

In just 40 seconds, this 3D body scanner will capture your body's circumference measurements, body composition, posture analysis, Body Shape Rating (BSR), Basal Metabolic Rate (BMR) and shows you how you compare health-wise against others of your gender and age. You can find 3D body scanners like Fit3D mainly in gyms, health clubs, and fitness studios.

Q.bio $3495/membership

This "physical of the future" makes it easier to pick up on signs of disease at the earliest stages. Membership is steep at the early adopter stage but includes a whole body MRI, genetic analysis, biochem analysis of your blood, saliva, urine and vitals and a super-detailed but easy-to-understand readout and review of all your body's organs: your heart, brain, uterus… The non-invasive scan can detect changes linked to common cancers, cardiac, neurodegenerative, metabolic diseases and more.

Talking to Vanity Fair for her newest film Lee, Kate Winslet revealed one project she wishes fans asked about more is Iris. The 2001 film stars Kate as a young Iris Murdoch against Judi Dench's older counterpart. And for Kate, nothing was more terrifying than working with such a wonderful actress.

"People don’t really ask me about Iris. It’s such a delicate film," she says. "It was the first thing I had done after having my daughter. Going to work with a baby, I’m playing Iris Murdoch, looking to Judi Dench’s older Iris Murdoch — I was sh—ting myself."

Considering how nervous I get when I meet my heroes, I can only imagine what it was like to meet Dame Judi Dench. Talk about a dream! Another film Kate loves is Revolutionary Road, and not just because she got to reunite with Leonardo DiCaprio.

"The thing that people say is, 'You got to work with Leo again.' Then they go off on the whole Leo tangent, which I totally understand," she says of the film, which follows an ambitious couple who find themselves trapped in the reality of 1950s suburbia. "But Revolutionary Road — f—king hell, it just knocked us all sideways. Unbelievably difficult material. I was very proud of that film and what Leo and I were able to create as Frank and April. It was so brutal."

The process for getting Lee into the world sounds equally brutal, considering Kate started working on it over a decade ago. As producer, Kate tells Vanity Fair she doesn't mind the fact she's done more for the film than if she only had an acting credit. "That has felt very necessary for this film. But it’s also just really important to me," she says. "It’s important to me that people know that it’s out there and might feel compelled to go and see it."

Because it turns out, commercial success or stardom on its own doesn't actually help your movie get made! "It doesn’t matter who you are," she says. "No one’s going to go, 'Oh, I’ll just back that pony because she was in Titanic.' It doesn’t happen that way, and I never expected that. That’s really important to say."

"I've gotten older and I’ve learned more and felt more confident in myself about whether or not I could actually do it," she adds. "It’s not something I would’ve done had I not felt so passionately about the subject, and Lee was just—she wouldn’t let me go."
