hris Brown may have escaped the watchful eye of Rihanna on Tuesday night. After numerous sightings of him at the same clubs as his ex, Brown was out with his girlfriend, model Karrueche Tran, at SoHo hot spot Greenhouse, this time without RiRi. Spies said the two arrived with a group. Busta Rhymes, Trey Songz and Fabolous sat with Adrienne Bailon nearby. Rihanna and Brown, in town promoting his new album, “Fortune,” have been “accidentally” meeting up in clubs all week.
