Rihanna and Chris Brown Hook Up?

Rihanna and on and off boyfriend Chris Brown are back on and in a beautiful setting, New York gossip reports reveal they used the bathroom of the NYC Nightclub Griffin for a little make up time and a hook up.

According to the NY Post, the pair were both at the nightclub with friends at separate tables and Chris approached Rihanna's table and began dancing for her.

The report claims that the two then wound up on the dance floor before retiring to the club bathroom and locking the door behind them.

The Post reveals:

"Observers saw them go into the bathroom together, and when RiRi emerged, “She seemed a little ruffled” a source said.

We’re told the pair, who broke up after Brown hit Rihanna during a fight before the 2009 Grammys, partied together until 4 a.m., when he left with his pals and she split five minutes later."

Further reports state that the pair were locked in a bathroom together for 30 minutes while two bodyguards guarded the door.

A friend of Rihanna's told Hollywood Life: "It was on and cracking. They hooked up. I wasn't in the bathroom with them but I know they f****d around and what not."

"They were in the club partying hard, had some drinks and kush and one thing led to another and that was that... He wanted her just as much as she wanted him."

Chris - who was charged with assaulting the pop star in 2009 - has made no secret of his close relationship with the 'Diamonds' singer, and the pair even shared a public peck on the lips at the MTV Video Music Awards last month.

Eyewitnesses have taken to twitter to comment on the couple's reconciliation, with fellow club-goer @kandibecool posting: "Btw, Chris Brown and Rihanna are def together or at least hooking up... Saw it 1st hand (sic)".
