Is Rihanna dating Knicks' J.R. Smith?

Amid an onset of some pretty weird behavior (e.g., tweeting a photo of her arm with an IV drip), Rihanna has apparently found time to cozy up to a new man.

According to In Touch Weekly, the 24-year-old pop star has been seeing Knicks forward J.R. Smith, 26. On a recent night out at the NYC club Veranda, the two "were very flirty in the club all night and holding hands," an eyewitness told In Touch.

"She was sitting on his lap and was really into him," the spy said.

In March, Smith was fined $25,000 by the NBA after tweeting a photo of a scantily-clad woman in his bed.

"He is the team's most controversial player, so it's no wonder that Rihanna likes him," says a source about the songstress, who had said in the past that she goes for bad boys.
