Up and coming pop stars Justin Bieber and Selena Gomez collaborated for the song “One Less Lonely Girl” on Dick Clark’s “New Year’s Rockin Eve” on December 31. American Idol’s Ryan Seacrest hosted the show.

Justin came out to lead off the performance. He worked the crowd with theatrics, hand gestures, dance moves, and–of course–singing. He continued to work the crowd and hit the notes, which made the teeny bopper girls scream. Then, about a minute and half through the performance, a guy walks Selena Gomez onto the stage so she could act like Justin’s girl during his performance.

He gave her a hug and started serenading her. As she started bopping a little bit to the song, Selena appeared to enjoy the performance. Selena got up and started dancing along with the other back-up dancers towards the end of the act. He ended it, by thanking everybody and giving Selena a big hug.
