That was quick. Just as Rihanna and Chris Brown were getting increasingly public with their relationship, the pair, affectionately dubbed "Chrianna" by Rihanna's Navy and Team Breezy, may well have called it quits.

E! Online reports that prolific tweeter Rihanna hinted at a split over the microblogging site on Tuesday (Dec. 10). After Brown was photographed wearing a hat from his ex Karrueche Tran's clothing line in Paris -- where he was rumored to be hooking up with Tran -- Rihanna tweeted, "Goodbye muthaf---er," then promptly erased it (however, it's still on her Instagram). She followed with another subsequently deleted post, writing, "You give, you get, then you give it the f--- back. Examine what you tolerate."

Still, other sources say Rihanna isn't too miffed about the whole thing. (And she shouldn't be, considering she and Breezy were reportedly hooking up while he and Tran were still together.)

An ineloquent insider told Hollywood Life, “Rihanna is not stupid and she know [sic] his little side piece is there but she ain't tripping on the small s--- and trust, it’s really small. Ri don’t even pay attention to that because there’s no point," the source added. “She would never give time or spend a second thinking about another b---- that’s not even in her same league," the source continued. "Come on now, there’s really just no comparison and she could care less about another b---- or where they are in world because she and Chris know what time it is!”

Ah, young love. Here's hoping they work it out, because laser tattoo removal stings.
