Yesterday was a very strange day! Not only was it Rihanna‘s birthday, her and ex-boyfriend Chris Brown both released remixes of their songs with each other on them. Rihanna released a remix of “Birthday Cake” with Chris on it and Chris released a new version of “Turn Up The Music” with Rihanna doing a verse and singing the harmonies with him. I’m not really sure what they’re trying to do here but it’s kind of musical marketing genuineness if you think about it. The real question here though is… are they back together?
