Rihanna to Chris: keep on tweeting

Chris Brown is back on Twitter and that's thanks to Rihanna. The "Nobody's Business" singer told Chris to ignore the haters and brush off the negative comments made by comedian Jenny Johnson. As HollywoodLife.com previously reported, Jenny spoke out for the first time since instigating a nasty Twitter rampage last week that resulted in Chris shutting down his Twitter account. On Nov. 30, the comedian shared her thoughts in an essay she wrote for GQ, "Chris Brown Quits Twitter: The Comic Responsible Responds."
