Reportedly, Rihanna left Jay Sean’s album release party because C. Beezy was played.

According to MirrorCoUK, Cash Money records broke the bank to secure Rihanna as guest of honor at their lavish UK launch party.

Rihanna, who was in London ahead of her incredible performance on X Factor, had barely sat down when the DJ played a track by her ex, Chris Brown.

So she gathered her posse and stormed off.

It left party organizers fuming. Well, they had spent lots of money on Cristal champagne to impress their VIP guest at the Friday night bash, thrown to celebrate the launch of Jay Sean’s album, All Or Nothing.

Rihanna, who was wearing a slinky, cleavage-enhancing trouser-suit, hugged pal Jay and apologized for being late. Minutes later she was grooving to his performance of Down and then the DJ suddenly spoiled her good mood.

Hearing her ex being played, Rihanna alledgedly stopped dancing, returned to her table, told her entourage the party was over and left.
