No really, don’t wake him up. Chris Brown—currently on tour in Europe for his newest album—lashed out at comedy writer Jenny Johnson on Twitter Sunday, spewing a plethora of misogynistic, vulgar tweets at the former TV producer. Johnson, named one of 2012’s 25 funniest people on Twitter is known for using Brown as Twitter fodder. The brawl began with a simple tweet from the pop star: “I look old as f--k! I’m only 23…” To which, Johnson sent the reply: “I know! Being a worthless piece of shit can really age a person.” Brown's bold responses prove he doesn't need back up. But if he did, Rihanna—judging by her Twitter—has got his back.
