Most people blow out a few candles on their birthdays, but Rihanna, who turns 24 today, seems determined to start a full-on fire.

In the wake of Chris Brown’s controversial return to the Grammy stage last week (many people — like Miranda Lambert — were uncomfortable that Brown, who pled guilty to felony assault after a fight with Rihanna the night before the 2009 Grammys, was welcomed back to the show and given two performance slots), the “We Found Love” singer has been playing awfully nice with her ex.

Earlier today, Chris Brown tweeted, “HAPPY BIRTHDAY ROBYN” (Rihanna’s real name is Robyn Rihanna Fenty), to which she quickly replied “Thanks!” The small exchange was enough to launch a thousand blog posts asking whether Rihanna should be interacting so benevolently with her former beau, whom many feel has not demonstrated adequate or genuine remorse about his past iniquities.

But a moment ago, Rihanna took the reconciliation (and thus the controversy) a step further when she tweeted out a remixed version of Chris Brown’s single “Turn Up The Music” that features her own vocals as well. She wrote, “Turn up the music remix #RihannaNavy #Teambreezy enjoy!!!” and attached the video below:

It seems appropriate that the video contains nothing more than the word “YIKES!!!!!!!!!” in all caps because that’s bound to be the reaction that many listeners have when they realize that Rihanna and Chris Brown have not only made amends, but are now working together on new music as well. Although the two stars may wish for us to “Turn up the music” and just dance, it’s hard to forget about the harrowing leaked images of Rihanna’s swollen face that we all saw in 2009.

The song hits the net mere moments after a remixed version of Rihanna’s own track, “Birthday Cake,” which features Chris Brown, arrived online. Yes, you’re reading this correctly: Rihanna and Chris Brown each debuted remixed version of their own tracks featuring each other at the exact same time. Even stranger, the coordinated effort seems to be a sort of rogue operation, with the singers sending out links for free downloads.

“Its a download OVERLOAD!!!!,” Rihanna tweeted. “Working on more links for u guys, so errbody could have some #CAKE” The song is likely to be taken down from various sites quickly, but, for now, you can hear it below.What do you think? Is it inappropriate for Rihanna be making music with Brown? Is it her job as a public figure and victim of domestic violence to serve as a role model to her young fans, or do you think it’s time for critics to drop the controversy altogether and just move on?
