Birthday Cake REMIX - Rihanna featuring Chris Brown

The feature on Rihanna’s  remix to “Birthday Cake” is none other then ex-boyfriend, Chris Brown. 

Sources tell Info that Chris Brown laced the track and will be seen in the music video. Breezy  sings and rhymes on the track as none other than the pop superstar and recent grammy winner can, but we’ll have to wait till next week,the official release date, to hear if both parts will be included. 

Over the weekend, Chris Brown and Rihanna were seen leaving a West Hollywood studio, separately. Co-producers of “Birthday Cake,” Da Internz — comprised of Kosine and Tuo — hinted on the collaboration when they told MTV News that the cameo on the track would “shock the world.” 

“It’s gonna be crazy,” Tuo said. “And the feature on there is gonna shock the world,” Kosine added. 

The icing on the cake is that Brown did indeed attend Rihanna’s 24th birthday celebration on Monday night (Feb. 13). Sources say the singers came together and were close the entire night.
