As we informed you a couple of days ago, Chris Brown and Rihanna got back together again, though not romantically. He is the “shocking guest” on her “Birthday Cake” remix.

You can listen to the track above, but *please note that discretion is recommended as it contains some instances of language that might offend.

Neither Chris nor Rihanna said anything about the collaboration when word of it got out online, even prompting Billboard magazine to write an open letter to her, pleading her to push him out of her life.

Now that it's out, the two are probably getting ready for the backlash.

One thing is certain: you can expect one, especially given the way these two parted ways. Three years ago, Brown beat Rihanna to a pulp in a fit of rage.
