It looks like Rihanna just can’t keep away from Chris Brown — even if he is supposedly dating model Karrueche Tran. The infamous exes were spotted at NYC nightclub the Griffin this week “hugging and kissing,” a source tells Celebuzz. “And they went to the back of the club alone together.” And Brown was spotted early the next morning sneaking out of the hotel where Rihanna is staying. The public displays of affection did not go over so well with Tran, apparently. “She felt the kiss was a public slap in the face,” a source tells Us Weekly.
