Rihanna who? Chris Brown and Karrueche Tran shared a passionate, sunset embrace on Monday ... and she made sure everyone saw it on Twitter, too.
The singer and aspiring model, who have been together about five months, appear to be going strong. "Head over heels," she wrote beneath the pic.
In this intimate, romantic shot, Karrueche Tran and Chris Brown are seen kissing lovingly, with idyllic backdrop of the beach at sunset behind them:
No response to this social media territory-marking from Rihanna, who may or may not have been with Tran earlier this year via Facebook and Twitter.
In a March 3 TwitPic, Rihanna took what some people interpreted as a racist shot at Tran, who is half-Vietnamese, writing "Ima make u my bitch."
The pic was a bag of rice cakes dressed up in gold earrings and black shades.
This followed rumors that Rihanna and Chris Brown, who recently collaborated on two remixes together, had been secretly hooking up for over a year.
Tran's response? A Tweet directed to no one in particular, but clearly in reference to Rih, saying, "I'm Angeline [sic], you're Jen. C'mon you see where Brad is at."
It's completely unclear how much Rihanna cares, but Karrueche's latest Twitter salvo leaves little doubt that Chris Brown is hers ... for now. Congrats?
