Is Rihanna getting some overtime in with her basketball-playing ex-boyfriend?

Rihanna went out clubbing with girlfriends in NYC in the wee hours of April 24 and ran into her ex, New York Knick player J.R. Smith, whom she hung out with throughout the night, according to Hollywood Life.

“Rihanna arrived with her girlfriends at Greenhouse around 1 a.m.," says a source. "Rihanna had security escort her down to the DJ booth table where Iman Shumpert and ex-boyfriend and bad boy J.R. Smith were sitting."

"The Knicks players had just beat the Celtics and they were out celebrating," continues the source. "It was really clear to everyone that there is some awkward tension still between RiRi and J.R., but she was dancing really sexy in front of him, showing off almost."

The two — who are rumored to have dated last spring — even spent some time in the VIP section later on that night.

"J.R. later went up to VIP and sat with Rihanna for a bit after she got on the mic to shout out to the NY Knicks, ‘the greatest team in the world,’ big win,” adds the insider.

However, the source points out that Rihanna and JR did not leave together.

"Rihanna left with her girls (no guys) around 4 a.m., out the back door and went back to their hotel, Gansevoort Park," says the source. "Rihanna stopped by J.R.’s table on her way out to give him a kiss and a hug." 

So should Chris Brown be nervous? We doubt it, since it sounds like nothing too hot-and-heavy happened between Rihanna and J.R. at the club. 

In other words, we're thinking Chris is still in the game.
