Has the R&B singer forgiven her ex-boyfriend?

Well, perhaps not completely, but at least they are reportedly friends again. Rihanna has apparently invited Brown to make a guest appearance on a remix of her new single, Birthday Cake.

It is only just past 3 years ago when Brown assaulted his then girlfriend, on the eve of the 2009 Grammys. The altercation landed Chris, now 22, a conviction and a restraining order, and saw him sentenced to hard labour.

Since the restraining order has been relaxed, Rihanna appears to have forgiven Brown, even though others may not have just yet. His presence at the Grammys, and Best R&B Album win upset many celebrities and music fans on the third anniversary of his and Rihanna's incident.
