Chris Brown's Girlfriend "Pissed" About Rihanna VMA Kiss

Brown Didn't Even Tell Her He Was Going to the Awards Show!

To be honest, we can't understand what any woman would see in Chris Brown. But we can see why model Karrueche Tran, who has for some reason chosen to be his girlfriend, is none too pleased about the very public smooch he shared with former flame Rihanna at the MTV awards Thursday night.

To recap, after Rihanna accepted the Video of the Year award for "We Found Love in a Broken Place," she headed back to her seat, but first made a pit stop over to Brown. The two former lovers - who infamously split after Brown beat the crap out of her in February 2011 - then shared an embrace for the whole world to see.

Now, in the wake of their kiss, Tran is reportedly seeing red. "She felt the kiss was a total slap in the face," a source tells Us Weekly, who added that Brown didn't even tell his girlfriend he was going to the awards in the first place. "[Karrueche] and Rihanna really hate one another and Chris ultimately just does what he wants. Seeing him with Rihanna at such a public event made her very angry."

Us also alleges that Brown and Rihanna have been carrying on a hot and heavy affair behind Tran's back for months. Tran and Rihanna, meanwhile, have carried on a very public feud for quite some time, attacking and threatening each other over Twitter.

Ladies, we're here to tell you he's not worth it. You're both beautiful, smart and talented. It's time to grow up and move on!
