Rihanna Single, Again

Pop icon Rihanna's tweet has sparked speculation that her rumored relationship with Chris Brown has come to an end.

The singer wrote on Twitter: "Being single sucks. The only thing I get to do anymore is whatever the f*** I want to do."

Rihanna had grown closer to ex-boyfriend Brown in recent past. He was accused of physically assaulting her in 2009.

Brown was recently seen partying with many girls in Paris and invited his ex-girlfriend, model Karrueche Tran. This upset Rihanna.
