Justin Bieber & Ariana Grande go viral!
Remember when everyone was lip syncing to Call Me Maybe on Youtube? Well brace yourselves! It's happening again and we have The Biebs and Ari to

They lip sync along to Carly Rae Jespen's new single, I Really Like You with a couple of their celebrity friends. So far we've spotted Lance Bass from Nsync and Kendall Jenner.
