The two R&B superstars have been attached at the hip the past few weeks, but are they making it official - forever?

Four years ago, the time of the Grammy Awards spelled disaster in the lives of Rihanna and Chris Brown. On Monday night, it could have been not be more different for the power couple. The female hit maker attended the event with her beau, and they were both in a good mood the entire night as they watched the show and posed for pictures. Looking dapper in an all-white suit, Brown seemed happy to spend the night with his peers and on-again girlfriend, and she was equally smitten.

Rihanna's powerful performance at the Grammys was an incredible showstopper as the songstress took to the stage in an incredible rendition of her newest single Stay. Joining her was Mikky Ekko who complemented the famous singer well. Although her vocals were fantastic and she looked stunning in a floor-length Azzedine Alaia dress, the one thing on everyone's mind as the performance wound down was the spakling diamond ring on her left ring finger.

No doubt, the implication of an engagement will create a buzz in the industry, seeing as both Brown and Rihanna are two of entertainment's biggest and most newsworthy names. Reports of domestic violence between the two leaked to the public in 2009 led to their breakup, and their recent public reconciliation - there were speculations they never completely lost touch - was met with disbelief and criticism.

Rihanna defended her decision to get back with Brown in an interview with Rolling Stone magazine.

"Even if it's a mistake, it's my mistake," she pointed out. "After being tormented for so many years, being angry and dark, I'd rather just live my truth and take the backlash. I can handle it."
