Chris Brown's Girlfriend Upset Over Rihanna VMAs Kiss?

By Sowmya Krishnamurthy

The kiss seen 'round the world apparently has rubbed one person the wrong way. Chris Brown and Rihanna's recent kiss and embrace at the MTV VMAs has apparently annoyed Brown's girlfriend Karrueche Tran.

According to US Weekly Karrueche is "totally pissed off" by the smooch.  "She felt the kiss was a public slap in the face," the source told US, claiming that Brown decided to attend the VMAs last minute without letting his girl know.

We reported earlier that the "Turn Up The Music" singer — who has reportedly become close to Rihanna again — made eye contact with his ex. She walked over to greet him and they shared a quick embrace. Then, Rih Rih patted Brown's bleach-blond head and walked away.

Last month, Rihanna sat down with Oprah Winfrey's OWN network and opened up about her tumultuous relationship with Chris, saying that he was the "love of my life," but that they are now working to reconcile their friendship and are still "very close." When asked about being romantic with her ex, Rihanna denied the rumors, citing his new relationship with Karrueche. "He's in a relationship of his own. I'm single but we have maintained a very close friendship," she told Oprah. "We've just worked on it little-by-little. And it's not easy."
