One star who won't be stripping down any time soon: Gwyneth Paltrow.
The actress, 37, says she lost her waif body after pigging out on fried chicken and ice cream sundaes while filming Love Don't Let Me Down in Nashville.
"The director, Shana Feste, didn't want me to have any definition whatsoever, so I had to stop working out… I was so bad with the food and alcohol in Nashville," she tells the May issue of Harper's Bazaar.
"If you saw me naked compared to what I looked like when I did Iron Man 2, where I was eating so well and exercising everyday…" she adds. "I'll get it back together, but I just have never eaten so much fried food and white flour in my life, ever."

Paltrow recently told British Vogue she could nosh on "whatever I want, as long as I exercise… which is just as well, because if I put the word 'diet' into my brain, I immediately gain a stone [14 pounds]."
She's opening a London exercise studio with trainer Tracey Anderson (clients include Jennifer Aniston and Courteney Cox) later this year. Anderson helped her drop 20 pounds of baby weight after welcoming son Moses, 4. (She is also mom to Apple, 5, with husband Chris Martin.)
"I had to work hard to get it like this," Paltrow says of her bod.
