Chris Brown: Loving Rihanna-Karrueche Tran Tension!

The ladies in Chris Brown's life, girlfriend, Karreuche Tran, and ex-girlfriend, Rihanna, may or may not be trading social media barbs in an escalating public feud.

Either way, he's loving life these days.

Maybe it’s a welcome distraction in Brown’s life now, with the iPhone theft investigation and all. Maybe it's just nice to have his ego stroked. Maybe both.

In any case, Brown and Rihanna have reportedly been hooking up for months, despite him dating Karreuche Tran ... called “an open relationship” by some.

However, (perceived) trouble began when Rihanna tweeted a photo of a bag of rice cakes with gold earrings, and the caption, "Ima a make u my bitch."

Some interpreted that as a racial jab at Karrueche Tran, who is Vietnamese.

Maybe she was just hungry after a show? Who knows. But in return, the aspiring model fired off several missives on Facebook aimed directly at Rihanna.

In one, she wrote:

"Let me clear the air, if you have fenty at the end of ya name or your default Is Rihanna you have a better chance of winning the lottery than ending up on my friends list."

BAM. Oh, but it continues.

Just to be sure Rihanna (and/or the general public) got the message, Tran wrote: "I'm Angeline [sic], you're Jen. C'mon you see where Brad is at."

Meanwhile, Brown is loving every minute of this.

“This is all very flattering to Chris. Name me a 21-year-old red blooded male that wouldn't love having two women fighting over him," a source said.

NOTE: We can't actually find a Karrueche Tran Facebook page that looks authentic, or any proof of Rihanna egging her on. So interpret this as you will.

Given the suggestive nature of Brown's collaborations with Rihanna, and the fact that he was at her birthday party, you do have to wonder, however ...
