Jimmy Kimmel vs. Kanye West

After milking his "feud" with Matt Damon for laughs, late-night host Kimmel got into an actual feud with rapper West. It all started after Kimmel debuted a sketch on his show in which children re-enacted an interview West gave to BBC Radio 1. West then went on an all-caps Twitter rant against Kimmel during which he said Kimmel's ex Sarah Silverman was "a thousand times funnier than you and the whole world knows it" and also demanded an apology from the host. What happened next was ratings gold: West appeared on Kimmel's talk show to publicly end their feud. "A lot of people think you are a jerk. I often in my own personal conversations say, 'No. I know this guy. He is not a jerk,' " Kimmel said. For his part, West said he had directed all his frustrations about tabloids and the media to Kimmel.

Nicki Minaj vs. Mariah Carey

The American Idol feud that started in fall of 2012 continued well into 2013. Reports surfaced before the season even premiered that Minaj and Carey weren't getting along during the auditions, and video surfaced of a heated exchange between the two during which Minaj could be heard yelling: "I told them I'm not f---in' putting up with her f---in' highness over there." In 2013, viewers got a look at what went down in Charlotte, N.C., during which Minaj stormed out after the two got into a heated debate over a contestant. While neither of them is returning to the judges panel next season, the feud continues. In November, Carey told New York radio station Hot 97: "Honestly, I thought it was gonna be a three-person panel. They gave me a nice dangling monetary moment,” she said. While she didn't name Minaj specifically, she added: “It was like going to work every day in hell with Satan."

Sinead O'Connor vs. Miley Cyrus

After O'Connor wrote an open letter to Cyrus, during which she cautioned her about letting herself be "pimped" by the music industry, Cyrus responded by mocking O'Connor's mental health issues of two years ago with screengrabs on Twitter. "Before there was Amanda Bynes," Cyrus wrote of the actress, who has battled her own mental health issues. Hours later, O'Connor wrote a second letter criticizing Cyrus for posting tweets from a time when "I was unwell and seeking help" but not indicating they were two years old. "I mean really really … who advises you?" she asks incredulously. "Have you any idea how stupid and dangerous it is to mock people for suffering illness? You will yourself one day suffer such illness, that is without doubt. The course you have set yourself upon can only end in that, trust me." The feud continued with more letters and tweets until O'Connor threatened legal action unless Cyrus apologized. O'Connor later explained to Time: "The music business is corrupt, a spiritually corrupt arena. It’s full of nothing but vampires and pimps, honestly. You couldn’t understand it unless you were in it. The only way to survive it is to love music."

Lady Gaga vs. Perez Hilton

The former friends took their feud public by trading insults on Twitter over the summer. She accused him of being a stalker, while he denied that and said he was receiving death threats from her fans. In November, she revealed the cause of the disagreement: "He started asking me really terrible questions, and he was being very negative about Born This Way, and we had had a lot to drink," she told Howard Stern in an interview, referring to questions that suggested her third studio album was a failure. “He was supposed to be my friend and I felt betrayed, so I started crying. And then my friend had to come in and pull the camera out; they wouldn't turn the cameras off. And then he apologized, but I sort of felt like it was like, 'But I'm Perez Hilton so I'm allowed to treat you this way.' I looked at him and said, 'Just because you are who you are does not mean that our friendship doesn't mean anything when the cameras turn on. So, now I see who you really are.' And I was done after that.”

One Direction vs. The Wanted

It was a battle royal on Twitter between the British boy bands when The Wanted's Thomas Parker tweeted at One Direction's Louis Tomlinson in April: "You even talk about us at your own gigs. Are you that upset you didn't get in this band?" To which Tomlinson replied: "Pal, we both know I wouldn't waste my time auditioning for your band. You humour me with your bad boy persona." That continued for a while (and their girlfriends even got involved). But in August, The Wanted's Nathan Sykes indicated that all was right in boy-band land, telling MTV News: "I think both ourselves and One Direction are, as far as I'm concerned, whatever kinds of words were said since I wasn't really part of it, think it kind of [went away now,] which is awesome. I think it's the best people really concentrate on the success that we're both having and how well [we're doing], which is always great."

Kim Kardashian vs. Katie Couric

In August, a reporter asked Couric about the Kardashian phenomenon. "I don’t understand -- why are they so famous? I think it’s mostly teenage girls that are interested," she replied. Kardashian responded by posting a photo of Couric's baby gift congratulations card given to her and her now-fiance Kanye West. The reality TV star, who welcomed a baby girl, North West, in June, hashtagged the image: "#IHateFakeMediaFriends  #MayIHumblySuggestYouNotSendGiftsThenTalkS--t." Later that day, Couric replied in a statement to E! News that she was merely answering a question posed by a reporter: "I was responding to a reporter's question, and explaining how I'm intrigued by the public's fascination with her family. I didn't mean to hurt her feelings. The gift is genuine, and I'm happy for Kim and Kanye," read Couric's statement to E! News

Chris Brown vs. Frank Ocean

Who hasn't Brown feuded with? Following last year's bar brawl with Drake, this year the troubled singer and his entourage engaged in a brawl with Ocean and his entourage in a parking lot outside a Los Angeles recording studio in January. Ocean allegedly blocked Brown from pulling out of a spot, TMZ reported, and a fight broke out after Brown attempted to shake Ocean's hand. Ocean said the brawl left him with a cut hand, but he declined to press charges. "As a child I thought if someone jumped me it would result in me murdering or mutilating a man. But as a man I am not a killer," he wrote. "I'm an artist and a modern person. I'll choose sanity. No criminal charges. No civil lawsuit. Forgiveness, albeit difficult, is wisdom. Peace, albeit trite, is what I want in my short life. Peace."

Jennifer Lawrence vs. Joan Rivers

During a live Q&A with Yahoo CEO Marissa Mayer in November, Lawrence took a jab at Rivers' E! show: “There are shows like the Fashion Police that are just showing these generations of young people to judge people based on all the wrong values and that it’s OK to point at people and call them ugly or fat.” Rivers struck back with several comments, including this one given to the New York Post: “I love that she’s telling everyone how wrong it is to worry about retouching and body image, and meanwhile, she has been touched up more than a choir boy at the Vatican. Look at her posters. She doesn’t have a nose, she has two holes. She just has to learn, don’t talk if you’re doing it.”

Amanda Bynes vs. Everyone

The troubled starlet used Twitter to lash out at a slew of stars -- from Rihanna to Jay Z to Modern Family's Sarah Hyland -- before she started treatment for mental health issues in July. After Courtney Love -- who knows a thing or two about struggling with issues in the public eye -- tweeted at Bynes, "pull it together, dude," Bynes fired back: "Courtney Love is the ugliest woman I've ever seen. To be mentioned by her at all makes me and all my friends laugh!" And when Jenny McCarthy retweeted reports that police were at Bynes' New York apartment, Bynes replied: "you're ugly! Police weren't at my house old lady! Shut the f--k up!" and "Aren't u 50 years old? I'm 27, u look 80 compared to me! Why are you talking about me?" Both later apologized to each other.

Katy Perry vs. Chief Keef

Another day, another Twitter feud in Hollywood -- but this one turned threatening. In May, Perry referenced a song by 17-year-old Chicago rapper Chief Keef, saying that the title “I Hate Being Sober” caused her to “have serious doubt for the world.” The offhand remark caught Keef’s attention several days later, at which point he issued a violent and profanity-filled response. “Dat bitch Katy Perry Can Suck Skin Off my D---,” he wrote. “I’ll smack The S--- out her.” Keef also revealed plans to release a new song targeting Perry. The songstress quickly apologized on Twitter. “Mr. Keef! I’m sorry if I offended you. I heard a lot of people guesting on the song & didn’t even know it was you in particular,” she wrote. “I’m a fan of your ‘Don’t Like’ video tbh. I was really just having a general opinion on our generations [sic] desire to be constantly intoxicated.”
