Chris Brown and Karrueche Tran back together? Singer Wishes Ex Happy Birthday

Less than a month ago, Chris Brown announced his split from on-again, off-again girlfriend Rihanna. Soon after the announcement the singer was reportedly spotted with his ex-girlfriend Karrueche Tran. The two had no problem publicly flirting now that Brown was single again furthering igniting rumors that the two were trying to rekindle their relationship.

Recently, Tran tweeted a picture she posted on her Instagram that shows her putting her naked butt in Brown's face on her birthday last year.

She captioned the photo "TBT my birthday last year. Who's face am I gonna put my a** in this year? Lmao I'm kidding."

Brown then tweeted Tran happy birthday to his ex-girlfriend which she responded with a simple heart.

"I wouldn't say Karrueche and Chris are back together but they are talking and kicking it," Hollywood Life reports.

Brown has been caught in a sticky love triangle with Tran and Rihanna. Brown began dating Tran in 2011 after his split from Rihanna. Brown and Tran dated for a year before he dumped the aspiring model to get back together with Rihanna. A lot of people were shocked the two were dating again after the 2009 incident where Brown was charged with two felonies and allegedly beat Rihanna on the night of the Grammys.

After a couple months of dating, Brown announced during a radio interview on "The Kyle and Jackie Show" that he was single.

"I can't really be focused on wife-ing somebody that young," Brown said.

Rihanna responded to the radio interview by posting pictures on Instagram with cryptic messages geared towards Brown that ignited a Twitter war-of-words.

Recently after announcing the split, Brown and Tran were spotted hanging out together.
