Nikki Reed fought back tears onstage at a Twilight event in Los Angeles on Saturday as she declared her love for the franchise's devoted fans.

More than 2,000 campers have set up tents outside the Nokia Theatre L.A. and Reed admitted that she was overcome with emotion as she thanked the crowd for their support.

Before debuting All I've Ever Needed, a song she wrote for The Twilight Saga: Breaking Dawn - Part 2 soundtrack, Reed said: "This is the last one (movie) and I feel really sad. It's hard to find the words to describe what this whole experience has meant to me. I just love you guys!

"I love you guys and I don't ever say that because I always feel that's weird to say to a bunch of people... I mean, I say that to Paul, but it feels weird to say that to a bunch of people I don't know, but I love you guys."

Her co-stars Jackson Rathbone and Ashley Greene also attended the concert, while Twilight author Stephenie Meyer spent three hours signing autographs.
