Justin Bieber and former mentor Usher embroiled in ‘heated exchange’ at Oscars afterparty

Okay, so I’ve been following everything, and apparently, it was Usher who went to Justin first – not the other way around! People who are really in the know are saying Usher was pretty fired up, even a little angry, when he talked to Justin. But they swear, swear it never got physical, even though some other sources are spreading rumors about a full-on fistfight. Honestly, I think it was just a heated discussion, and those other people are just trying to stir up drama!
