{babes} Fanning, Stewart reunite in 'Twilight'

LOS ANGELES -- Kristen Stewart is kissing and telling about her co-stars.

Asked who's better at locking lips -- Robert Pattinson or Taylor Lautner -- she doesn't hesitate. "Dakota (Fanning). I think that's the safe answer."

She's referring to The Runaways, the biopic released earlier this year in which the pair cavorted -- on stage and off -- as jail-bait rockers Joan Jett and Cherie Currie.

Being quickly reunited for the latest Twilight sequel, Eclipse, took some getting used to, admits Fanning, 16.

"During the summer, when we were doing The Runaways, we both had in the back of our minds that she would have to go do Eclipse pretty much right away," says Fanning, who originated the role of sadistic Volturi immortal Jane in last year's The Twilight Saga: New Moon. "I came a month or two later, just for a week, to do my part. But, it was so weird, just seeing each other in different costumes and being different people because we got so used to seeing each other as Joan and Cherie, especially with her having the short black hair.

"She has green eyes in real life, so she had brown eyes again and long hair, it was so weird. Obviously, our relationships are very different in The Runaways and Eclipse. That was kind of fun, but it was really, really weird at first."
