Kristen Stewart shows off her sexy side in a black, retro bikini for the November cover of GQ UK, shot by famed photographer Norman Jean Roy. The Twilight actress is known for her usual uniform of tied-up tee shirts and skinny jeans, but inside the magazine Kristen talked about her personal transformation. Kristen said, "I looked like a boy for a long time. . . Now I feel like a woman."

Kristen is gracing the cover of two high profile publications this month, also posing for Glamour to promote the first installment of Breaking Dawn, which hits theaters Nov. 18. For now, Kristen's attention has been focused on a non-Twilight project. Kristen's been overseas filming Snow White and the Huntsman for the past two months but soon she'll reunite with Robert Pattinson and Taylor Lautner for the latest international press tour.
