Los Angeles: Singers Rihanna and Chris Brown reportedly indulged in a war of words after the former texted ex-boyfriend Drake.
Rihanna recently announced her patch-up with Brown after their break up in 2009. However, things were not smooth between them during the 55th Grammy awards ceremony Feb 10.
"Chris and Rihanna had a big bust-up at the Grammy over Drake. She was messaging him and Chris saw and it didn`t go down well," the sun.co.uk quoted a source as saying.
"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," the source added.
Drake and Brown were involved in a brawl in June 2012 and it was said to be over Rihanna.
