Just days after Chris Brown broke up with Rihanna, the Fine China singer was spotted partying with his ex-girlfriend Karrueche Tran, again.

Enstars reported last week that while Rihanna was on her Diamonds World Tour during the same weekend as Brown's birthday, Tran partied the night away with her former lover at the Emerson Theatre in Los Angeles on May 5. 

Recent reports indicated that Brown performed at Wild 94.9's annual Wild Jam in California on May 9, which Tran was spotted there too.

Paparazzi snapped pictures of the former couple. In one particular picture that went viral, Brown appears to be touching Tran's butt.  The picture has raised speculation on whether or not the two are rekindling their romance.

"She's not mine if she's everybody else's," Brown tweeted on May 9. 

Meanwhile, hours later, Rihanna tweeted: "Got a thang for a King, but chu ain't a King!!!" No indication on if she was referring to Brown. 

Despite the break-up, Rihanna seems to be enjoying her days without Brown just fine. 

The Nobody's Business singer has been posting pictures to her Instagram account of her and her friends. 

"It's up and down sometimes, the s**t is even sideways. Everytime some s**t pops off between them, they blast that s**t all over social media, and they shouldn't," the source said. "But when they're far apart, that's how they act out towards each other when one of them doesn't get their own way. It's crazy as f**k, but it's how they get down."

In an interview with 2Day's The Kyle and Jackie Show on May 5, Brown confirmed the breakup with Rihanna.

"I mean, at the end of the day, shawty doing her own thang, she on the road. It's always gonna be love. I'm a grown man, just gotta fast forward," Brown said.
