Is there still tension between Chris Brown’s exes, Rihanna and Karrueche Tran? Spies said Tran didn’t make it past Pink Elephant’s velvet rope last week, because, her rep explained: “she was told she could [not] attend said club, because Rihanna was inside. [She] decided to go elsewhere.” A rep for Roee Nahmani’s hot spot added, “She wasn’t let in as a courtesy to Rihanna. To keep the peace, they decided it was in everybody’s best interest if they weren’t on the dance floor at the same time.”
