Chris Brown and Rihanna, back together? It’s certainly looking that way, after the couple were spotted smooching at New York City nightspot Griffin this week. Just one week after Brown and Nicole Scherzinger were forced to play down rumors of a romance, the ‘Run It!’ singer appears to have reignited his controversial relationship with Ri-Ri.

According to the reliable folk at E! Online, Brown was initially joined by Bow Wow at his own table inside the club, before Rihanna arrived and sat in a separate booth. Later in the evening, Brown climbed over to join Rihanna at her table before somewhat bizarrely taking off his shirt. It seemed to do the trick though because before long, the former couple were dancing and making out. Brown eventually left the club just before 4am, with Rihanna following suit around five minutes later. Representatives for both stars are remaining suspiciously silent on the story and let’s not forget: Brown is still on probation for beating the Barbadian singer before the Grammy Awards in 2009. Nevertheless, they have remained close and even shared a friendly kiss at the MTV Video Music Awards last month.

Brown’s girlfriend Karrueche Tran was noticeably absent from the club this week, though Dave Chappelle, Tyson Beckford and Chris Rock were all in attendance. In a further twist, one eyewitness claims to have spotted Rihanna and Chris Brown leaving the Gansevoort Hotel together the following day. Coincidence?
