It appears that Chris Brown and Rihanna have parted company once again after an argument at the 2013 Grammy Awards over Rihanna's ex-boyfriend, Drake.
The couple had allegedly argued because Brown caught Rihanna texting Drake during the ceremony.
A source told the Sun: "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."
The endless on again off again relationship between the pair looked to have hit another stumbling block.
They were seen leaving the Grammys looking unhappy and were recently spotted at opposite ends of the same club, seemingly ignoring each other.
The source continued: "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.”

Rihanna recently told Rolling Stone that she was giving Brown one last chance. She said:"He doesn't have the luxury of f**king up again. That's just not an option.
"I can't say that nothing else will ever go wrong. But I'm pretty solid in the knowing that he's disgusted by that. And I wouldn't have gone this far if I ever thought that was a possibility."
