Sounds like Rihanna has a new "rude boy" in her life. Rumors are spreading like wildfire that the 'Where Have You Been' singer has been getting hot and heavy with New York Knicks player JR Smith.

The Boombox reports that RiRi has been engaging in quite a bit of PDA with the Knicks' bad boy. A spy told InTouch that the pair hung out at New York City's Veranda nightclub and dished, "They were very flirty in the club all night and holding hands. She was sitting on his lap and was really into him." Ow ow!

Smith is one of the most controversial players on the New York team and is frequently in trouble -- which seems to be just Rihanna's type, however unfortunate that may be. Smith, who has two kids, plead guilty to a reckless driving charge in 2009 (the same year Rihanna was dealt blows from her bad boy ex, Chris Brown), earning himself a month in jail, 500 days of community service and a seven-game suspension from the NBA. Further adding to his dangerous appeal? Smith was fined $25,000 for tweeting a photo of a thong-clad model in his bed -- and later shut down his old Twitter account after rumors spread that he wrote in the same style as the Los Angeles-based Bloods gang. Sounds like a winner to us!

We bet mentor and Brooklyn Nets co-owner Jay-Z won't be too pleased about RiRi's new romance -- though he's probably just relieved that she's not with Breezy!
