Actress ASHLEY GREENE struggled to cope with her new-found fame after the success of Twilight because her celebrity negatively affected her relationships with her closest friends.

Greene became an overnight star in 2008 after landing the role of Robert Pattinson's sister Alice Cullen in the vampire film franchise, but as the 25 year old tried to come to terms with her new life in the spotlight, she worried she was at risk of losing her best pals.

She tells Marie Claire magazine, "It was a hard adjustment going from zero to 100 in a day. But it was also hard to talk to (friends), because you don't want to be a jerk (and brag).

"After the movie came out, some people said, 'You changed'. And I said, 'I haven't changed, dude. Your opinion of me has changed because I'm working on this film.' Trust me, my parents would let me know (if I changed)."
