LOS ANGELES — Kristen Stewart has apologized for comments she made in British Elle in which she compared her paparazzi photos to images of women being raped.

"I really made an enormous mistake – clearly and obviously," the 20-year-old actress told People. "And I'm really sorry about my choice of words."

Stewart's comments were in response to how she's handled fame since the enormous success of the Twilight franchise.

LOS ANGELES — Kristen Stewart says it was an easy decision to cut her locks to portray rocker Joan Jett in the upcoming feature film The Runaways.

"It was something I needed to do," the 19-year-old actress told MTV News at the film's premiere Thursday night in Hollywood. "I needed to feel the sweat coming down my face; I needed to be able to touch it."

Stewart says the hair chop was actually a bigger deal for her co-star in the film, Dakota Fanning, who "almost cried" at the transformation.

"I did; I almost cried," Fanning admitted. "For some weird reason, I had an attachment to Kristen's hair. But [her new look] was amazing, and it was what she wanted. It's not my hair!"

LOS ANGELES — Kristen Stewart and Robert Pattinson have a hard time agreeing on a lot of things, including which one of them is the most romantic.

"I have a no-bulls--- detector, so I'd have to say Rob is," Stewart tells Harper's Bazaar for the magazine's December cover story. "I think romance is anything honest. As long as it's honest, it's so disarming."

When told Stewart had pegged him as the more romantic of the two, Pattinson responds: "No. I'm better at faking."

The Twilight pair also draws a line in the sand when it comes to choosing which has the bigger ego.
