4 stars bare all for 'Allure' annual nude issue

Time to get naked.

"This is the first interview I've ever done where I'm not wearing panties. Lucky you," says Kristen Bell, 33, who candidly talks about being "self-conscious" about her "belly skin" by posing naked after having a baby. Daughter Lincoln turned 1 last month.

She joins Jenna Dewan Tatum, Minnie Driver and Nia Long in posing for the May issue of Allure magazine, on newsstands April 29. It's the annual issue featuring nude stars.

"I was a little bit nervous, but I actually really love my body — it's done amazing things for me," says Driver of the experience. "There's such a grace to being confident in who you are."

Jenna Dewan Tatum's hubby, Channing Tatum was completely supportive of her stripping for the magazine less than a year after the birth of their first child. Says Jenna, 33: "Chan was really on board with it— he knows I'm very comfortable in my own skin."

Being nude in a magazine is not new to Nia Long, 43, who shed all for Ebony in 2011.

"I'm still going naked. I can still take it of off two babies later. When you have kids, your body changes drastically, and we have to learn to appreciate ourselves as we are. My boobs are not the same as they were before; I'm not going to lie."

And for Minnie Driver, 44, the timing was right. "I never could have done this when I was 25. No way. All I saw were the flaws. I still see flaws, but I see what's great more— and I've got a banging body."
