Nikki Reed, Christina Perri on stage for Camped-Out Fans next saturday @THR.

THR  While Twi-hards eagerly await the Los Angeles premiere of The Twilight Saga: Breaking Dawn -- Part 2, with many fans already camped-out outside Nokia Theatre, Christina Perri is providing a bit of early entertainment.

The singer, featured on the film’s soundtrack with “A Thousand Years (Part 2),” will hit the stage for a live concert on Saturday right outside the theater beginning at 1 p.m. The two-hour show -- hosted by Time Warner Cable -- will also include a performance by Twilight actress Nikki Reed and her American Idol husband Paul McDonald, whose duet “You’re All I Ever Needed” is featured in the film’s ending credits. Anya Marina and A Boy and His Kite will also perform.

TWC has also enlisted the help of several Breaking Dawn cast members to dish out a free continental breakfast for fans on Sunday at Chick Hearn Court and Georgia Street. In addition to a free bagel and juice, fans will also be gifted with a free Twilight T-shirt and goodie bag.

Atlantic recording artist Perri recorded the smash hit single “A Thousand Years” for The Twilight Saga: Breaking Dawn -- Part 1. Her follow-up includes updated lyrics sung over the same whimsical tones.

Reed, a first-time contributor to the soundtrack, tells The Hollywood Reporter that her song “was my way of showing the fans that this film has really inspired [me].”

Paul and I have a very strong connection,” she adds. “It’s very easy for us to write love songs together that have a very similar feel to this film and, I think, evoke the same emotions. We wrote it about Bella and Edward and about each other.”
