They were together and now they may not be. Word has it Rihanna may have dumped Chris Brown on Instagram. Chris was kicking it with his ex Karrueche over the weekend and we guess that didn't sit too well with Rihanna. She apparently got so mad, she thanked fans for supporting their situation, but vented as well. Here's part of what she instagramed “Being single sucks. The only thing I get to do anymore is whatever the f**k I want to do." Wow, that relationship didn't last, until maybe next week when they are back in photos together!
