Open Image ModalShannen Doherty has a reputation as Hollywood's bad girl and feuded with nearly all of her "Beverly Hills, 90210" castmates, and yet it was her feud with Alyssa Milano that will go down as the worst. The "Charmed" co-stars began fighting on set during the third season and it was reported that Shannen was jealous of Alyssa's popularity. Tension ran high on set and things grew so heated, producers had to bring in a mediator to resolve their issues. When they couldn't work things out, Shannen left the show. (credit:Getty)
Mariah Carey vs. Eminem(10 of25)
Open Image ModalIs there anyone Eminem hasn't feuded with? Eminem and Mariah Carey began to spar after he claimed that they used to have a sexual relationship. Mariah denied the relationship, telling Larry King, "I hung out with him, I spoke to him on the phone. I think I was probably with him a total of four times. And I don't consider that dating somebody."Mariah later mocked his claim in her video for "Obsessed," which featured an Eminem look-alike who was obsessed with her. The rapper retaliated with a number of songs that mentioned Carey and threatened to release nude photos of the singer as well as voicemails to prove they dated. In the song "The Warning" he raps: "Shut the fuck up before I put up all the phone calls you made to my house when you were "Wild N' Out" before Nick, when you was on my dick and give you something to smile about."

Open Image ModalMiranda Lambert was not happy to see Chris Brown performing at the Grammy Awards. "And Chris Brown Twice? I don't get it. He beat on a girl...Not cool that we act like that didn't happen," she tweeted referencing Brown's brutal 2009 assault on Rihanna. Brown responded indirectly by tweeting, "Hate all you want because I got a grammy now! That's the ultimate f*** off."Then at her concert, Lambert held up a handwritten poster that read, "Take notes Chris Brown" and said to the audience, "Listen, I just need to speak my mind. Where I come from, beating up on a women is never OK. So that's why my daddy taught me early on in life how to use a shotgun."Brown fired back in a series of tweets: "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!" (credit:Getty)

Open Image ModalRihanna and Ciara -- who both dated Chris Brown in the past -- got into a heated public spat in February 2011. First Ciara made a dig at Rihanna on "Fashion Police," saying: "I ran into her recently at a party. She wasn't the nicest. It's crazy because I've always loved and respected what she's done in fashion. It wasn't the most pleasant run-in." When Rihanna heard what Ciara had said, she fired back on Twitter. "My bad Ci, did I forget to tip you? How rude of me.... You gangsta huh? Ha." They volleyed insults and threats at each other and then Rihanna called a truce."Ciara baby, I love you girl! You hurt my feelings real bad on TV! I'm heartbroken! That's why I retaliated this way! So sorry! Let's make up." Ciara accepted the apology and that was that. (credit:Getty)
Kourtney Kardashian vs. Farrah Abraham (19 of25)
Open Image ModalThis might be one of the most ridiculous celebrity fights of all time. "Teen Mom" cast member Farrah Abraham didn't think things through when she criticized Kourtney Kardashian on Twitter. "I'm shocked Kourtney Kardashian is pregnant again Did she not learn anything from TEEN MOM? Maybe its a fake pregnancy like kims wedding SAD," she tweeted.Kourtney was understandably confused by the attack and tweeted back, "Why would I have anything to do with Teen Mom? I'm 32 years old! I may look young, honey, but don't get it twisted." While Kourtney suggested that Farrah had no idea what she was talking about, the "Teen Mom" star couldn't resist firing back at her: "Guess what! Age and money honestly do not change a person's poor choice. Quit making excuses," she tweeted. Kourtney's boyfriend Scott Disick also got in on the fight, sarcastically tweeting at Farrah, "We're not teenagers, ya f**king moron." When asked if he knew who she was, he responded, ""I just thought she was some shit stain on Twitter, no?" Sadly, this Twitter fight actually continued with Farrah later tweeting, "4 all who mistunderstood: regards to kourtney K.~I hope she takes her relationship w/her boyfriend more serious 4 their children-takecare." Shortly after, however, she couldn't resist getting one more word in with a jab at Disick:"Caught wind of these dramatic articles, w/ loser scott disick or some boyfriend of kourtneys, is Shit Stain < racist 4 black?" she wrote. "Great dad! NOT." (credit:Getty)
