Better sharpen your claws, ladies, ’cause this is one nasty catfight! Karrueche Tran is furious after Chris Brown’s latest fling, Cydney Christine, dissed her so publicly, has EXCLUSIVELY learned. Read more on their juicy feud, here.

Karrueche Tran, 28, and Chris Brown, 27, aren’t even together anymore, but that won’t stop haters from hating! “Karrueche is furious that she’s being dragged back into Chris’ drama-filled world once again,” a source tells EXCLUSIVELY. “She wishes he and his THOT of the week could just leave her alone.” We should have known their Instagram-based beef wasn’t going to blow over!

In case you missed it, the rapper’s latest fling, Cydney Christine, threw major shade at Karrueche on a public Instagram post in Oct.. When a Karrueche fan dissed Cydney for going on a date with Chris, his new girl pulled out her boxing gloves and fired a shot right back! “Karrueche gonna beat your a–,” the fan commented, to which Cydney replied, “She can try LOL.” Technically Cydney didn’t start the fight, but she sure wasn’t shy about defending her new romance with Chris. The rumored couple were spotted hanging out at Halloween Horror Nights — supposedly the SAME night Karrueche was there. Talk about a freak show!

Even though Chris appears to be enjoying himself with Cydney, there’s one huge secret that he’s keeping from her. “He still calls Karrueche constantly and tries to hook up with her, but she’s not down with that at all,” the source continues. “Karrucehe has moved on.” Chris is kind of known to be a player, and was even messing around while dating Rihanna, so we’re glad to hear that Karrueche isn’t interested anymore. We can totally understand why Karrueche is frustrated at the moment, and Chris should really do his best to keep this beef at bay. We don’t want another Kanye West vs. Jay Z fiasco on our hands!
