Look who's popped out of RiRi's 'Birthday Cake'!

Yes after her producers Da Internz revealed that the feature on the remix will "shock the world", the rumour merry-go-round went into overdrive with one name firmly in the frame... Chris Brown.

Well now that rumour has come true as it looks like Rihanna has finally put their well documented incident to bed.

It's also no coincidence that this is released at the same time Brown has released his 'Turn Up The Music (Remix)' (here) featuring, yep you've guessed it... Rihanna!

The 2 are sending a clear message to the world that they have buried the past and are happy in each others company.

Check out the track below and let us know what you think.
