Rihanna And Chris Brown's 'Birthday Cake' Remix: Fans React

'People have to get past that 'incident' in '09,' one fan tweeted.

On Monday night, Chris Brown and Rihanna dropped the long-prognosticated remix to Ri's "Birthday Cake," from her Talk That Talk album. The duo also dropped a remix of Brown's Fortune track "Turn Up the Music," all on Rihanna's 24th birthday.

The producers behind the "Cake" track, Da Internz, promised that the remix would "shock," and they didn't lie. Considering that it was just three years ago that Brown assaulted Rihanna over Grammy weekend, the two coming together for the sexy duet marks a new chapter for the singers, one that has been met with varied reactions from fans.

On one side of the argument are fans who appreciate the song regardless of the singers' past.

Like most of us do ... they have grown up and moved past that time. Role model or not ... RIHANNA CAN'T LIVE FOR HER FANS ... SHE LIVES FOR HER!! And the sooner you delusional ignorant idiots realize that, the quicker they, along with everyone else who's quick to judge, can move on. LEAVE THEM ALONE!!!"

Sandra D. had a similar reaction, writing, "I realllyyyyy loved BOTH Cake and the Turn Up The Music remix. They took a bold decision, but I believe it will show the world that it is finally time to move on and get back to making great music! LOVE Chris' music video to Turn Up The Music too!"

KringleChick wrote, "Loving both of these songs. Glad they were able to put the music first and let everything else stay behind. Both are great artists and these songs rock. Their voices are amazing together!"

For other fans, however, their past is hard to ignore, and many readers met the release with disbelief and anger, citing the 2009 assault. "Why, Rihanna? Why?" LP54 wrote. "I know for lots of people it's just a song, but for others it's their role model saying it's okay.

Whether Rihanna likes it or not she is a role model. Her making this song is telling those girls that you can go back to him even if he has abused you. Chris has nothing to lose from this but she has sponsors, fans, and support from the media. With two songs, Riri could lose a lot."
