Rihanna has hinted that it's all over with Chris Brown - with a message about being single on Twitter.

The singer posted an 'R Card' which read: "Being single sucks. The only thing I get to do any more is whatever the f*** I want to do."

Chris, 23, pleaded guilty to assaulting Rihanna, 24, in 2009 but the pair later reconciled.

Rihanna was recently reported to have been infuriated after the Don't Judge Me singer was pictured partying with scantily-clad girls on tour and enjoying a meal with his ex-girlfriend, model Karrueche Tran.

She later tweeted: "Never underestimate a man's ability to make you feel guilty for his mistakes."

The "single" tweet conflicted with a report that Rihanna and Chris were to spend Christmas together in a £14 million Barbados holiday home.

The Daily Mirror said that the singer, 24, is renting the six-star apartment close to the Sandy Lane resort in her native Barbados.
