Return Of The Ex… Karrueche Tran Shares A Raunchy Tweet Of Herself And Chris Brown

Chris Brown and Rihanna have only just broken up (again, again), but that didn't stop Brown's ex Karrueche Tran getting a little cheeky on Twitter with him for her birthday.

The fashion designer and model tweeted a photo of herself and Brown for her 24th birthday, writing, "TBT my birthday last year. Who's face am I gonna put my ass in this year? LMAO I'm kidding".

The photo shows Tran showing off her bare derriere into Brown's face. Nice.

Chris also tweeted the star for the big day.

Brave move Karrueche, we would not like to be an enemy of RiRi's...
