Chris Brown wants to show the world that he's back with Rihanna by joining her onstage at the Grammys, according to RadarOnline. Rihanna is already appearing in promotional ads for the February 10th awards show, but Chris reportedly thinks a duet will show the world that he's a "changed man."

A source told the website, "Chris wants to perform with Rihanna at the Grammys to show the whole world they are back together. Chris doesn't care what the haters say, and wants to give the viewers an over the top performance with Rihanna."

The source added, "He wants the fans to know this is the real deal, and he is a changed man. If Rihanna can forgive him, the rest of the world should move on from what happened four years ago."
