Pop punk Pink, actress Rachael Leigh Cook and pregnant former wrestler Stacy Keibler have stripped for a new magazine photoshoot to celebrate beauty at the age of 34. The trio has joined TV stars Dania Ramirez and Laura Prepon to pose for People magazine's Naked at 34 feature, which was inspired by a recent study, which suggested that women feel best about their bodies at that age. Pink admits she learned to love her body as a child, training as a gymnast, and now she is teaching her daughter, two-year-old Willow, the importance of self-acceptance. The singer says, "She said to me the other day, 'Mama, on Tuesday I think we should get naked and have a naked booby butt dance party'. I was like, 'I'm in'." Meanwhile, newlywed Keibler, who is expecting her first child with husband Jared Pobre, is learning to embrace her new curves as she adjusts to motherhood. She tells the publication, "Being pregnant really gives me a confidence I didn't even know I had. Just yesterday, I asked my husband, 'What do you love most about my body?' and he said, 'Your growing belly'." And new mum Cook, who gave birth to daughter Charlotte in September (13), reveals she agreed to strip off as a keepsake for her future self: "I'm here for 90-year-old me. I'm here so that future me can look back and be like, 'Hey, you were all right'."
