(CBS) Chris Brown and Rihanna's new musical collaborations just, and already has fans in a Twitter frenzy.
Brown sings on the remix of Rihanna's explicit song "Birthday Cake," and she's featured on the remix of his tune "Turn Up the Music."
The fierce reaction stems from their history together. In 2009, Brown attacked then-girlfriend Rihanna at a pre-Grammy Awards party. He pleaded guilty to a felony charge and is serving five years of probation, but the two have seemed to put the past behind them for their new tracks.
Many fans have taken to twitter to react to the unexpected collaboration. Comedian Paul Chowdhry joked about the reunion tweeting:
Unless Rihanna and Chris Brown's new track is called, 'If you like it then you shouldn't have put your fist on it' I'm not interested.Paul Chowdhry (@paulchowdhry) February 21, 2012
Perez Hilton, like many other fans, loved the collaboration and applauded the two for moving on.
Music heals! It really does! #MusicHeals!!! It has the ability to turn what was something destructive into something creative and positive!Perez Hilton (@PerezHilton) February 21, 2012
P. Diddy's son, Justin, agreed with Perez tweeting:
That Birthday cake remix w CBreezy is fire!!!!!!!!!!Justin Dior Combs (@JDior_) February 21, 2012
Other fans disagreed, saying the collaboration does not set a good example. "Rhi need counseling. Not collaborating," a fan tweeted.
"Rihanna is sending a message to victims that it's cool to forgive abusers. NOT something to be celebrating," another said of the collaboration.
