Though the duo was reportedly supposed to spend Sunday together before Rihanna's performance at the Staples Center in Los Angeles, Breezy spent the night before dancing with this mystery woman.

Chris Brown recently opened up to New York radio station Power 105.1, saying that he was concerned his on-again off-again Bajan lady Rihanna would be unfaithful.

"I'm just a regular guy so I be thinking, man I hope nobody's hitting that," Brown said. "But you can't be the jealous boyfriend, I can't be calling her constantly asking what she's doing, so I just gotta put that trust out there and hope nothing happens."

However, after seeing these pictures, it appears Rihanna is the one who should be concerned.

Witnesses at the club say Brown left the club with several girls and piled into two limos.

Brown has been making headlines pretty regularly the last few weeks. On Friday he was in court over allegations that he falsified community service documents. The singer was required to perform community service as a part of his probation stemming from his 2009 felony assault of Rihanna.

However, in spite of the domestic violence incident, Brown and Rihanna had appeared to reconcile. He recently visited "On Air with Ryan Seacrest" and opened up about his brutal beating of his current girlfriend and how he won her back.

"I just tried my best to be the best man I could be over the years and just show her how remorseful and sorry I was for the incident," Brown said.

The couple appeared to be back on track, according to Brown.

"It's still like we're kids," he said. "I try not to be too grown and be like, 'Let's have candlelight dinner every night.' I try to make sure everything is fun. It has to be fun and it has to be genuine."

However, who knows if that will last once Rihanna sees these pictures.
