Chris Brown, Karrueche Tran Back On? Exes Attend Birthday Together

Chris Brown and Karrueche Tran reportedly attended a mutual friend's birthday party on Saturday night, and a recent tweet has since sparked reports of a reconciliation. The reports came just two days after the singer confirmed that their relationship is over.

Brown and Tran are friends of singer Christina Milian, and Brown retweeted a message from one of his followers, which appeared to confirm reports that the exes attended Milian's birthday dinner. Various reports claim that they arrived together, although they have not yet been verified.

"#gumboofdayear @itsv0n @CMilianOfficial @chrisbrown@SeanKingston @Bighoodboss @KidRED_ @YoungLo @karrueche@lizziefmorris and many more," Brown tweeted on Oct 6.

The reconciliation rumors have stunned fans, particularly because Tran, 24, was said to be left furious and feeling betrayed after Brown, 23, dumped her over his ex-girlfriend Rihanna.

"Wtf is going on?" a confused Tran tweeted on Oct. 5 after Brown ended the relationship. She later tweeted "All I'm saying is.. You don't mess with people's genuine feelings. You just don't!"

On Thursday, Brown, who broke up with Rihanna in 2009 following a domestic assault incident, confirmed that he had ended his relationship with Tran over Rihanna. It fueled reports that he and the Bajan singer are back together.

"I don't want to see her hurt over my friendship with Rihanna. I have decided to be single to focus on my career. I love Karrueche very much but I don't want to see her hurt over my friendship with Rihanna," Brown reportedly told "I'd rather be single allowing us to both be happy in our lives."

Brown has been photographed spending more time with Rihanna, 24, publicly in recent weeks and new reports suggest that Tran believes that he had been cheating on her with there "We Found Love" singer.

Tran reportedly suspected that Brown was involved with Rihanna for several weeks because his behavior allegedly became increasingly unusual. The "Turn Up The Music" singer reportedly began going to nightclubs alone, acting distant toward Tran and increasing his public appearances with Rihanna, a source reportedly told TMZ.
