The status of RIHANNA and CHRIS BROWN'S relationship remains uncertain . . . but last we heard, it sounded like they'd broken up again. And now there's more evidence.
--Rihanna posted some pictures of a brand new Porsche that was purchased for her by JAY-Z and the ROC NATION crew.
--It even has a big "Roc Nation" bow on it, and one of the photos has the caption, quote, "Ain't nobody [effin'] wit my clique!! Thank you to my Roc brothers! I love you guys, y'all are crazy for getting me this bad ass ho."
--This car is worth between $150,000 and $200,000 . . . but it was probably worth it to Jay . . . because sources say he bought it for Rihanna as a reward for breaking up with Chris.
