For Allure's annual nude issue, it got four actresses to disrobe.

Jenna Dewan Tatum, Kristen Bell, Nia Long and Minnie Driver stripped down and showed some serious skin. Each actress spoke about feeling comfortable in their own bodies.

Kristen Bell, who is known for her humor on social media, said, "This is the first interview I've ever done where I'm not wearing panties. Lucky you."

She explained that her stomach area has always made her self-conscious, especially after giving birth. She also doesn't mind using a body double and is happy that it's an option she has. But she really wanted to pose for Allure to show she is comfortable with herself.

"I talk a big game about being comfortable no matter my size," she said. "I wanted to put my money where my mouth was."

She explained that when she was pregnant she felt happy with what she saw, and took up Pilates after her daughter was born.

Jenna Dewan Tatum, who also had a baby recently, said she just hoped she was in enough shape for the shoot. Her husband, Channing Tatum, was on board. She explained that when she danced with Janet Jackson, she would go to strip clubs with the singer.

"I don't know what it was, but she just really liked going to strip clubs," she said. "She's probably like, 'Thanks, Jenna, for telling the world I go to strip clubs.'"

The actress is not very inhibited, but she shared that during a dance recital, the strap of her costume broke off, and she ended up flashing the entire audience.

It took Minnie Driver some time to feel comfortable in her own skin.

"I never could have done this when I was 25 -- no way," Driver said. "All I saw then were the flaws. I still see the flaws, but I see what's great more -- and I've got a banging body."

She has posed nude before for Karl Lagerfeld, but she has also used a body double.

And Nia Long was exercising until the day of the shoot.

"I ran for 45 minutes this morning, and I haven't eaten a morsel," Long said. "As soon as this is over, I'm grabbing a burger."
