The Oscar winner took the title from her pop star pal Beyonce, who topped the publication's 2012 countdown, but Paltrow reveals her husband, Coldplay frontman Chris Martin, pokes fun at her status as a beauty icon.
She says, "Around the house, I'm in jeans and a T-shirt. I don't really wear make-up. That's what they're used to. He'll make a joke about it. If I've gotten fully dressed up, he'll be like, 'Oh, wow! You're Gwyneth Paltrow!' Because he's used to seeing me in like baggy shorts and frizzy hair."
Kerry Washington, Amanda Seyfried, Zooey Deschanel, Jane Fonda, Kelly Rowland, Drew Barrymore and Pink also feature on the list.
