Because you obviously can't get enough of 'Breaking Dawn,' here comes pop singer Christina Perri with a behind-the-scenes peek at the big 'Twilight' premiere in Los Angeles on Monday night. "I can't believe this is real life," self-described Twi-hard Perri told AOL Music. (Perri contributed the song "A Thousand Years" to the 'Breaking Dawn' soundtrack.) You can see Perri's own photos at Moviefone sister site AOL Music, and check back here all week for some expanded 'Twilight' coverage. Watch Perri's video for "A Thousand Years" ahead.
