Justin Bieber + Friends: Carlos Pena

Justin Bieber is one of the few teen pop stars today who's never had his own television show -- but that doesn't mean he doesn't love his fellow stars who used the silver screen to score hit records.

He's taken a special liking to Big Time Rush, particularly Carlos Pena. The Nickelodeon singer even joined Bieber and galpal Selena Gomez in their home video for Carly Rae Jepsen's 'Call Me Maybe.'
