No Rihanna/Chris Brown "split" ever lasts long, but they really do seem cursed when it comes to the Grammys. It was just before the Grammys in 2009 when they had their big fight, and now one rumor says their latest fight is over Rihanna supposedly texting her ex, Drake, at the Grammys.

A source told The Sun (via National Ledger), "Chris and Rihanna had a big bust-up at the Grammys over Drake. She was messaging him and Chris saw and it didn't go down well. Since that night they have barely spoken and have been doing their own things. For now they have split up but they will probably make up at some point."

They avoided each other at a nightclub the day before Valentine's Day, which was just a couple of days after the Grammys. But maybe it wasn't over Drake. Some folks put the blame on Chris's ex, Karrueche Tran, since she and Breezy were together at an event the night before. They are business partners through their fashion line, so they still see each other.

Maybe Drake and Karrueche should date, just to keep them both out of the drama. No one is safe when they hang out with Rihanna and Chris!
