Rihanna’s new boyfriend Karim Benzema is cheating on her with Chris Brown’s former girlfriend, Karrueche Tran, according to a report. Rihanna and Tran were both in on-again, off-again relationships with Brown.

Tran, who broke up with Brown in March after she discovered he had fathered a child with model Nia Guzman, is now rumored to be hooking up with Rihanna’s new boyfriend. The news comes days after reports surfaced that Rihanna and Brown were trying to rekindle their romance.

“Rihanna is Karim’s main chick, but Karrueche is side chick,” Life & Style reported, citing sources, according to Hollywood Life. “He’ll bring Rihanna to party with his friends and sleep over at his L.A. rental. [And] he’ll have his driver pick [Karrueche] up and bring her to him at a hotel.”

During the 2015 BET Awards at the Microsoft Theater in Los Angeles last month, Brown and Rihanna were seen getting along with each other years after the end of their tumultuous relationship. At the time, rumors circulated that Brown and Rihanna may be getting back together.

The “Four Five Seconds” singer defended Brown by calling his recent ex-girlfriend Tran “tacky and childish” for slamming him on social media. Rihanna, 27, supposedly didn’t think Tran was a good match for the “Loyal” singer and was happy that the two split up.

According to Hollywood Life, Rihanna told Benzema that she still loves her former boyfriend. The French soccer star reportedly got jealous seeing Rihanna’s “face light up” during Brown’s BET performance of “Post To Be.”

“Rihanna does like Karim and enjoys him a lot. He treats her well and he’s such a stud in everything he does,” a source told Hollywood Life. “She told him she won’t break his heart but did tell him she’ll always love Chris.”

However, the latest report of a budding romance between Benzema and Tran has not been confirmed.
