Who is More Sexy in Nude Ashley Tisdale, Keri Hilson, Bridget Moynahan and Kaley Cuoco (Allure?)

In Allure's annual shoot called "Baring All," Tisdale tells the magazine, "I'm 25, almost 26, but people think of me as much younger because I look young. Being in this shoot was me saying, 'I'm not just the young girl everybody thinks I am. I'm actually a woman."

"High School Musical" star Ashley Tisdale is all grown up.

Reality TV star Lauren Conrad graced Allure's annual "Nude" May issue -- fully clothed -- and talked about not knowing how sexy she can be. "I'm not a sexy person. I'm OK with it. I've never been the sexy girl. Whenever I've had a boyfriend, he's always been like, 'Oh, you're cute.'"

When I told my mom about the shoot, I left out the part about taking my clothes off." The 25-year-old star of The Big Bang Theory says of her preparation for the shoot, "My obsession is yoga, so I was already yogi-ing it every day," she says. "And I did veggies, raw food, and egg whites. So boring!" She was surprised by her own lack of shyness. "I was way more excited than I ever thought I would be. Which made me realize, I'm more comfortable in my own skin than I thought




KERI HILSON

Before all her hit songs, Hilson worked behind the scenes as a successful songwriter. Stepping out of the background was not as effortless as Hilson, 28, now makes it look. "The transition to being in front of the camera was very, very difficult," she says. "Everyone has their idea of what you should look like. 'You need to get into the gym.'
