How would you feel if your crush serenaded your best friend and not you?

That’s exactly what Justin Bieber did at Dick Clark’s New Year’s Eve special. The 15-year-old singing sensation brought Selena Gomez, 17, on stage while he performed his hit, “One Less Lonely Girl.” Looks like Demi Lovato, 17, who’s been Twitter-flirting (Flittering?) with Justin, was the lonely girl out in this love triangle. We wonder if Justin’s “swagger coach” has been teaching him a thing or two about the ladies, too. I mean, seriously, it takes a lot of swagger to ask Demi to “chill maybe grab a movie” and then sing up a storm on TV for her best friend, Selena. But, it doesn’t seem that Selena feels too bad about two-timing her friend as she tweeted after the performance, “had so much fun with @justinbieber Thanks for letting me join you on stage J :).” To which Justin responded, “@selenagomez good times…we did new years right…thanks for the love.” Way to rub it in, Selena! - Marta Topran
