Before you start speculating too much, know that this is still soundly in the "
rumor" pile. But sources are reporting that
Chris Brown might show up on an upcoming Rihanna song called "Birthday Cake," produced by Da Internz. According to MTV, the producers said the song was going to "shock the world," which sparked rumors on its own, but new developments in the story have come to light adding weight to the possibility.
TMZ is claiming that Brown, who was charged with beating Rihanna in 2009, appeared at her birthday party last weekend and tried to get guests to sign a confidentiality agreement. (Apparently he didn't try hard enough.) An unnamed source also told Miss Info that Brown would be featured in the song. However, Rihanna has not said anything alluding to the reunion. She did tweet that she needs "somebody #DIRRRTY" for the collab, suggesting Christina Aguilera will be involved. Do you think Chris Brown and Rihanna could potentially collaborate -- or is there just too much baggage there?
