Justin Bieber A Day

Biebs covered "3AM" and "You Got it Bad," before singing a snippet of his hit "Baby" during the lengthy performance. The star's vocal coach was being honored at the event, and she asked him to sing. Of course, he was honored to do it, and now everyone wants to see him rock out. The video of his performance is one of the hottest of the day! Does this surprise anyone?

We imagine the teen couple has gone their separate ways by now -- both have ridiculously busy schedules these days -- but expect them to appear at another red carpet event soon. Justin just announced he's up for three MTV European Music Awards, and we imagine he'll bring his gal as his date for that shindig. "Just got word that we got 3 MTV EMA Nominations for Best Male, Best Pop, Biggest Fans!! THANKS SO MUCH! LEt's VOTE!!!" he wrote on Twitter today.
