We can't believe it! In a recent interview with Glamour magazine (via Hollywoodlife.com), Kristen Stewart revealed that she panicked about revealing her bikini body in the latest Twilight instalment, Breaking Dawn!

Though the actress admits that she is "tiny" (sigh)., she also revealed how she "let herself go" on a previous film.

She explained: "I know I’m tiny. I did On The Road right before Breaking Dawn and I definitely did hang out a little bit. Then, when I was doing prep for Breaking Dawn, I suddenly realised, ‘this is SO not On The Road. People definitely want to see you looking trim.’ Usually we’re all making fun of Taylor Lautner for working out so often, and then suddenly me and Rob [Patinson] were running around the block while Taylor laughed at us."  (Teehee)

The countdown for Breaking Dawn is nearly here! We are so excited!
