Reason #2: If Chris Brown and Rihanna perform together at the 2013 Grammy Awards, we'll all be forced to talk about what happened the last time they made news at the Grammys.
If Chris Brown wants to let the world know that he and Rihanna are officially an item again, that's fine. But, if he does it at the Grammys, every single news outlet that covers the reunion will be forced to talk about what happened between the couple at the 2009 Grammy Awards. And, once again, we'll all be forced to talk about why their reunion isn't a good thing. That seems like the wrong foot to get off on if you're Chris Brown and Rihanna and you want people to take your rekindled love seriously.
