Miss Info reports that the remix of Rihanna's "Birthday Cake" will feature none other than...Chris Brown. Yikes.Rumors have been swirling that Rihanna had forgiven her ex after beating her severely in 2009, but many are still shocked that she would publicly welcome him back into her life and career.

Brown has been the subject of controversy since his Grammy Awards appearance Sunday where he performed twice and picked up an award for Best R&B Album.

Producers say the song will be released this week.
