Lmao... Some of you are TOO MUCH! He didn't sound that bad at all (though the "cry me a river" parts, and other parts where he tried to go higher, were strained), but the song was definitely recognizable, and he did go OFF at the end. You don't need to be starting out your day making such ridiculous overstatements.
I just want to know why he sang a BREAKUP song during his surprise appearance at his GIRLFRIENDS concert... I'm starting to think the relationship is more and more just for publicity
