Justin Bieber performed at the Staples Center last night, and his legions of teenybopper fans were treated to the first look at the trailer for his new film Never Say Never. "I might get in trouble for this, LA," he told the crowd. "I got a special treat for you guys!"

Bieber then showed the trailer to his fans, which documents his rise to fame and the early years of his life. We have to admit, the young Justin is pretty adorable -- who knew the little tyke would grow up to be one of the biggest pop stars on the planet?
