Ricci told Nylon Magazine, "We all have to be in bikinis in the second episode (and) some of the girls are like, 'I'm not dieting, screw it!' And I'm, like, totally dieting; I'm eating protein and vegetables and I'm doing my Pilates exercises at night, when I'm watching television."

"My Pilates instructor wrote out three different routines for me. I've worked out, 'OK, this one I can do in my dressing room, and this one in the studio at lunch...'"

Ricci also admitted to be fighting back acne. She said, "I use (acne cream) Proactiv because the lovely thing about my face now that I'm in my early 30s, I'm ageing, but I'm also dealing with acne, and now - this is disgusting - but I get it on my back. I'm like, 'What am I? A pubescent boy?'"

Ricci most recent film is "Bel Ami." She is starring alongside Robert Pattinson and she apparently thinks her co-star is quite hunky. Christina Ricci, 31, said about her "Bel Ami" co-star Robert Pattinson, "Oh, he's absolutely lovely. He's great in the movie. It's a very different role for him."

Watch out Kristen Stewart! She's all over your man in the latest film. To see photos go here.
