Justin Bieber performed on New Year's Eve in Las Vegas and brought along his friend, Selena Gomez.


Cutey, Justin Bieber, sung One Less Lonely Girl for Dick Clark's New Year's Rockin' Eve and surprised his fans when he brought Selena Gomez on stage. Lucky Selena sat on a stool while Justin sang to her. She sung along to the song and even joined in with the dancing at the end. Check out the video:

Selena looks more than happy to be sharing the stage with her good friend and we bet she was envied by all the female fans in the crowd. We think she looks gorgeous in her sparkly dress! Do you like Selena's outfit?

Poor Justin still has to wear his cast on his leg. What do you think of Justin's performance? Don't forget to buy the latest issue of Sugar. There's an exclusive Justin poster in LadMag.

After the performance, Selena tweeted: Had so much fun with @justinbieber Thanks for letting me join you on stage J :) Hope everyone had a wonderful New Years!”
