Rihanna and Chris Brown upcoming remix to “Birthday Cake”

It is no longer news that Rihanna and Chris Brown have something going on between them. The latest information indicates that the feature artist on Rihanna’s upcoming remix to “Birthday Cake” is none other then ex-boyfriend, Chris Brown.
According to sources, Chris Brown not only laced the track, he will also appear in the music video. Brown reportedly sings and rhymes on the track which will be released next week.
Chris Brown and Rihanna were seen leaving, at separate time, the West Hollywood studio where the remix was recorded.Co-producers of “Birthday Cake,” Da Internz – comprised of Kosine and
Tuo – hinting on the collaboration said that the cameo on the track would “shock the world.”
The icing on the cake is that Brown did indeed attend Rihanna’s 24th birthday celebration on the night of February 13. Sources say the singers came together and were close the entire night.
Prior to this latest development, reports were rife that the pop star and singer/rapper, who ended their relationship after Brown assaulted Rihanna in early 2009, have been privately hooking up for nearly a year.
Multiple sources also confirmed that the pair has been casually meeting up, even though Brown is currently dating model Karrueche Tran.
On February 8, 2009, Brown was charged with two felonies stemming from a brutal attack on then-girlfriend Rihanna that took place in his car. Both singers were scheduled to perform at the 2009 Grammys later that evening, and both performances were canceled.
Brown was sentenced to five years’ probation and six months’ community labor in Aug. 2009. A court order that forbid Brown from coming within 50 yards of Rihanna was lifted last February and in May, the pair began following each other on Twitter. “Its f—-in twitter, not the alter [sic]! calm down,” Rihanna told upset fans at the time.
