Like many people on Twitter, former news producer and current comedy writer Jenny Johnson (under her handle @JennyJohnsonHi5) frequently makes fun at the expense of controversial R&B; singer Chris Brown. But unlike most, Johnson found herself the target of an extended vulgar, sexist response from Brown on Sunday afternoon. 
 
 Johnson, who is often cited as one of the funniest presences on Twitter, has poked fun at Brown ever since his 2009 arrest for beating his former (and maybe current?) girlfriend Rihanna, largely due to his apparent lack of remorse. One of Johnson's most popular tweets, "Call me old fashioned, but Chris Brown should be in prison," was retweeted 1,869 times. 
 
 But it wasn't until she tweeted the following that she grabbed Brown's attention: "I know! Being a worthless piece of shit can really age a person. RT @chrisbrown: I look old as fuck! I'm only 23..." 
 
 Brown, who has 11.6 million followers on Twitter, responded by hurling sexual, graphic insults toward Johnson. (The full, NSFW exchange is below.) 
 
 This is hardly the first time Brown has found himself in trouble due to Twitter. Earlier this month, the singer posted a photo of himself dressed as a terrorist for Halloween, which many found to be racist. In fact, he's even gotten into it with Johnson (as well as a few other funny folks on Twitter) in the past, but never to such a disgusting degree. 
 
 After his performance at the Grammys earlier this year, Brown fired off aggressive tweets directed at his critics before deleting them. Whether he deletes this ugly episode with Johnson remains to be seen -- but don't worry, we have screengrabs just in case. 
 
 UPDATE: As of Sunday night, Chris Brown's Twitter account appears to be offline. 
 
 Again, the Twitter exchange below is very NSFW. 
 
 PHOTO GALLERY BEFORE YOU GO Chris Brown vs. Jenny Johnson PHOTO GALLERY Chris Brown vs. Jenny Johnson ||||| Miranda Lambert and Chris Brown have been battling in a public Twitter feud since the Grammy Awards last Sunday night. 
 
 On Monday, country singer Lambert, who is married to "The Voice" co-host Blake Shelton, tweeted: "And Chris Brown Twice? I don't get it. He beat on a girl…Not cool that we act like that didn't happen" 
 
 In 2009, Brown pleaded guilty for assaulting former girlfriend Rihanna and is now serving five years of probation. 
 
 Brown was applauded by the Grammy audience, which included Rihanna, for his performance and win for best R&B; album. His performance resulted in some very disturbing tweets from fans, including things like, "I'd let Chris Brown beat me up." 
 
 Brown responded to Miranda's tweet with one he has since taken down saying, "Hate all you want because I got a grammy now! That's the ultimate f*** off." 
 
 On Wednesday Lambert tweeted back, "I'm done for now. But not for good:) nite love bugs & remember… Be who you are an stand for what u believe in. NO MATTER WHAT!" later adding, "Oh and one more thing for all who are asking….I have a Grammy too:)" 
 
 In a concert Thursday night at the Amherst, Mass., Mullins Center, Lambert held up a handwritten poster that read, "Take notes Chris Brown" and said, "Listen, I just need to speak my mind. Where I come from, beating up on a women is never OK." 
 
 After the crowd applauded, she added, "So that's why my daddy taught me early on in life how to use a shotgun." 
 
 She then sang her hit song "Gunpowder and Lead," which is about a woman preparing to shoot her abusive husband: "I'm goin' home, gonna load my shotgun/ Wait by the door and light a cigarette/He wants a fight well now he's got one/He ain't seen me crazy yet." 
 
 Many of Lambert's songs, like "White Liar" and "I Wanna Die" are known to bash men. 
 
 In three separate tweets yesterday, Brown fired back, "Using my name to get publicity? I love it! Perform your heart out! Go buy @miranda_lambert! So motivational and "PERFECT." Goodnight to all the people who live life and who aren't stuck in the past!" 
 
 Lambert has yet to respond to Brown's tweets but Jack Osbourne, Michelle Branch and Eric Stonestreet have also expressed their disappointment in Brown's Grammy acceptance. ||||| Getty Image 
 
 With the way that Ebola is dominating headlines right now – despite Shep Smith’s best and most rational efforts – it would have been more surprising if nobody tried to fictionalize it. While my money would have been on Law & Order: SVU, it is instead Fox TV Studios that will be developing a series based on the work of author Richard Preston with producers Ridley Scott and Lynda Obst. The duo originally wanted to turn Preston’s bestselling book, “The Hot Zone,” into a feature film starring Jodie Foster 20 years ago, but the project obviously didn’t pan out. 
 
 The resurgence of Ebola, and especially the reported cases in the United States, has made the topic more relevant than ever, which is why Scott and Obst are back at work. 
 
 “I think it’s the speed with which it kills that makes the disease so frightening,” Obst tells The Hollywood Reporter. “People hoped it would stay in some remote part of the world. But that’s a fantasy in the modern world. The modern world makes us one big connected family.” 
 
 In regard to just the first chapter of “The Hot Zone,” Stephen King called it “one of the most horrifying things I’ve read in my whole life – and then it gets worse. That’s what I keep marveling over: it keeps getting worse. What a remarkable piece of work.” Keep in mind that it is a non-fiction thriller. Preston’s work in writing about Ebola isn’t limited to “The Hot Zone,” which examined the origins of this disease and similar viruses. In an article in the New Yorker last month, Preston recapped the “explosive” emergence of Ebola in West Africa, and that information will be included in the series, as will a piece that he has written for next week’s New Yorker that will cover the latest cases in the U.S. 
 
 Preston also conducted an AMA on Reddit for his August article in the New Yorker, and he answered a number of questions regarding everything from the experimental serum ZMAPP… 
 
 The antibody serum ZMAPP seems to be amazingly effective but we don’t know because it’s only been tried on the two patients. As for aftereffects, i interviewed Dr. Shem Musoke who nearly died of Marburg (close cousin of Ebola) and he told me it took him about a year to recover fully but now he was fine. It’s a crushing disease but if you survive you do recover. 
 
 … to how medical workers can avoid being infected while treating the disease. 
 
 They haven’t been able to fully protect themselves, doctors and nurses are dying. They’re wearing full protection biohazard suits, but the Ebola wards are just horrifying, 30 Ebola patients with one doctor and one nurse, both in space suits. Conditions are awful in those wards, we need more doctors and nurses – not even a space suit can totally protect you if the ward is really a mess. 
 
 According to The Hollywood Reporter, Preston has been working with Scott and Obst in the development of this limited series.
– You've probably had a burning desire to know what Chris Brown thinks about the Ebola outbreak, right? Well, the singer has finally made his theory known, and—surprise, surprise—it's a controversial one. He tweeted last night, "I don't know ... But I think this Ebola epidemic is a form of population control. S--- is getting crazy bruh." He then quickly followed that up, however, with: "Let me shut my black ass up!" (Brown recently admitted he's "made mistakes" and is "not perfect.") In other weird Ebola news ... this man is trying to make $150,000 off the outbreak.
