YO! JAY Z BLACK BALLED CHRIS BROWN FROM THE BET AWARDS!

MediaTakeOut.com told you yesterday that Chris Brown was supposed to perform at the Michael Jackson tribute. Well he was ... then BET changed its mind.

What happened you ask??? MediaTakeOut.com just got OFFICIAL CONFIRMATION that it was ALL JAY Z' doing. According to that insider, Jay Z SPECIFICALLY FORBID BET from allowing Breezy to perform. He told them that if they did neither he NOR BEYONCE would have performed.

Dang Jigga, we ain't know you were that vindictive ...
