ENGAGED SINGER BRIAN MCKNIGHT BUSTED

Hot Gossip is that R&B singer Brian McKnight has officially been BUSTED. Here's what popped off. A few weeks ago, Brian started Tweeting a woman back and forth (the woman was NON-BLACK, but you already knew that).

After weeks of flirting, Brian became COMFORTABLE ENOUGH with the chick to send over a pic of himself virtually nekkid. Anyways, the potential jumpoff's boyfriend hacked into her Twitter account, found out what was going on . . . and put Brian n BLIZZAST!!!

Can you say EMBARASSING!!!!
