Karrueche Tran, Rihanna NYC nightclub drama: Pink Elephant club kicks Karrueche to prevent Chris Brown drama

Karrueche Tran and Rihanna are in another beef after Chris Brown's girlfriend was denied club entry in New York City because the "Diamonds" singer was already in the club.

According to Page Six, Tran was not allowed access at the Pink

Elephant. Tran's rep stated, "She was told she could [not] attend said club, because Rihanna was inside. [She] decided to go elsewhere."

A rep for the nightclub 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."

The bitter feud between the women continues after being involved in 2012's most talked about love triangle with singer Chris Brown.

Sunday, the singer was spotted with Karrueche Tran for a toy drive after leaving his rehab for the charity opportunity. The singer tweeted before heading back to rehab, "Thank you to all the fans who brought gifts for the kids today. Have a wonderful holiday. You've made a merry Christmas for a young child!"

Is Rihanna bitter that he's back with Karrueche?
