Rihanna and her abusive ex-boyfriend Chris Brown have reportedly put their differences aside to collaborate on a remix of her song 'Birthday Cake', according to MTV News. The well-publicized altercation before the Grammys in 2009 landed Brown with a conviction, though the pair have allegedly reignited their friendship in recent months.
The restraining order has also been relaxed, and it appears the former couple have been taking the opportunity to see each other once again, with Rihanna inviting Brown to record vocals for the extended remix version of Birthday Cake. Producers Da Interz first fuelled the rumors of Brown's involvement in the project, saying, "It's gonna be crazy. And the feature on there is gonna shock the world". Rihanna has also done little to quell the rumors, hinting via Twitter on Friday (February 17, 2012), "They can say whatever, Ima (sic) do whatever... No pain is forever, Yup! You Know This". Brown has been courting controversy again in recent weeks, most notably at the Grammys Awards where he scooped Best R&B Album and later hit-out at his critics on Twitter.
Clocking it at only 1 minute 18 seconds, 'Birthday Cake' was initially not considered for inclusion on Rihanna's latest album 'Talk That Talk', however, due to a high level of fan interest following an online leak, it made the record as an interlude.
