Rihanna has hit out at Chris Brown over Twitter, posting a series of foul-mouthed tweets.
The singer, who split from Brown in 2009, is said to be 'fuming' after reports emerged that Brown recently got a tattoo of his new girlfriend's face.
Rihanna posted over Twitter: "Cuz of u I'm on some real f*ck a n***a s*it!"
U wanna be my main squeeze n***a, don't ya? So what n**a, I'm not tryna hear that sh*t!"
Brown assaulted Rihanna in 2009 during a fight. The singer was sentenced to five years' probation and six months of community service.
Meanwhile, Adele, Rihanna and Coldplay are set to perform at the BRIT Awards next month.
The London singer will make her UK live comeback at the ceremony after undergoing vocal surgery last year.
Noel Gallagher and Ed Sheeran all also confirmed to perform live at the ceremony, which takes place February 21 at London's O2 Arena.
