The cheek-kiss happened when Justin appeared on the American version of The Voice to premiere a clip from his Boyfriend video.
It seems slightly mad that he came on the show just to do that but you know those crazy yanks, their idea of entertainment is slightly different to ours.
Anyway, the kiss has caused quite a stir after some viewers noticed Christina’s less than enthusiastic face as Justin plants a smacker on her.
Yesterday the Dirty singer took to Twitter to deny the situation was uncomfortable, she wrote: "Haha! The media loves spinning stories… Can't a girl have a little #BieberFever after getting kissed by the Biebs?"
So that’s her face after something she enjoys? We really feel for her boyfriend, that’s not the kind of face you want to see after some sweet loving, is it?
