The war between Chris Brown's on and off girlfriends Rihanna and Karrueche Tran continues. Karrueche Tran, Chris Brown's current girlfriend, sent some Christmas shade over to Rihanna by posting a pic of her and Chris on her Instagram. This was only after Riri banned her entrance to a popular NYC club where the "Diamonds" star had arrived to first.

Oh girls, why can't we ever just play nice? Earlier this month Rihanna had been partying at NYC hot spot Pink Elephant. Karrueche arrived shortly after and was "told she could [not] attend said club, because Rihanna was inside," witnesses say "she decided to go elsewhere." A rep for Roee Nahmani's club told the New York Post that Tran "wasn't let in as a courtesy to Rihanna. To keep the peace, they decide it was in everybody's best interest if the weren't on the dance floor at the same time".

Karrueche, who claims to be a "mature person", says that "if the time ever did come where [she and Rihanna] would have to sit down and talk, [she] would do it". However, she adds, "I can work it out but that would be a lot" she told VIBE. Meanwhile she decided to get back at Riri by posting a lovable pic of Chris Brown gently kissing her cheek with the caption "Merry Christmas from us" on Christmas day.

Karrueche has stood by her man through his 90-day stay at a rehabilitation center, as ordered by a judged after violating probation on his 2009 Rihanna beating case. Although Rihanna was rumored to have also paid a visit to her on and off love, Karrueche has made it clear that her and Chris Brown are together. The couple also hopes that Brown is allowed a one day release from rehab to celebrate New Year's Eve together.
