Feuds are always nasty and with the advent of social media, they can become incredibly more public very quickly.

The battles can also escalate at record speeds, with those who are at odds trading insults only as quickly as it takes to compose a tweet of 140 characters or less.

When celebrities argue, however, it becomes even more epic as they flaunt their problems to the world -- insulting their enemies during interviews or when doing press tours. Some even take it in front of the cameras and have forever made feuding history.

Enstars compiled a list of eight celebrity feuds that have stolen headlines and are likely not to be forgotten:

1. Mariah Carey & Nicki Minaj: Season 12 of American Idol is not likely to be remembered for the performances by the contestants. Unless winner Candice Glover makes it as big as season one winner Kelly Clarkson did, no one will remember season 12 for her either. Instead, fans will remember the all-out brawl between judges Mariah Carey and Nicki Minaj. The two couldn't get along at all during the season, trading barbs at one another about their careers and judging abilities. Things got heated and out-of-control quickly after Carey alleged that Minaj had threatened to shoot her. Despite neither judge returning for season 13, the feud apparently hasn't yet died down. Though not directly mentioning Minaj's name, Carey told Hot 97 Radio in November that being on Idol "was like hell...going to work every day in hell with Satan."

2. Miley Cyrus & Sinead O'Connor: Cyrus didn't take it very well when O'Connor penned her an open letter on Facebook encouraging her to make better choices in life. The note came after Cyrus continued to make headlines for reported bad behavior and wardrobe choices. Cyrus responded by tweeting a screenshot showing some of O'Connor's tweets from two years ago when she was suffering from a mental breakdown. Cyrus captioned the screenshot "Before Amanda Bynes...There was....". O'Connor responded again by warning her that "taking me on is even more f*&kin' stupid than behaving like a prostitute and calling it feminism." The war has since claimed down but the two controversial singers did not make up.

3. Joan Rivers & Chelsea Handler: There has been no love lost between the 80-year-old Fashion Police co-host and the 38-year-old late night talk show host. Their feud has been going on for years but hit its boiling point in 2012 after they both appeared on Howard Stern's radio show. Handler went on the show first and said "Joan Rivers? What the f-k do I care about Joan Rivers?" Rivers came on shortly after and replied by saying that Handler only got to where she is by dating 56-year-old Ted Harbert, the CEO of Comcast Entertainment Group (which owns the E! Network her show is on). The couple dated for four years before splitting in 2010.

4. Donald Trump & Rosie O'Donnell: These two outspoken celebs famously butted heads in 2006 after O'Donnell called Trump a "pimp" and claimed he was using then-Miss USA Tara Conner's partying scandal as a publicity vehicle for his pageant. Trump retaliated by saying he could take O'Donnell's partner away, and called her a "fat pig" and a "degenerate" who is "unattractive." The two rehashed the battle on Twitter in 2011 and are reportedly still at odds.

5. Kanye West & Taylor Swift: Before the Yeezus rapper was dating Kim Kardashian, he made headlines in 2009 for interrupting Taylor Swift's acceptance speech for the Best Female Video at the MTV Video Music Awards. The rapper rushed the stage and stopped Swift's speech to say "Imma let you finish, but Beyonce had one of the best videos of all time. One of the best videos of all time!" While it didn't really spark a feud between the two singers, West did apologize to Swift for his rant and even reflected on it recently, saying he "wouldn't want some crazy drunk rock star cutting my daughter off also." Swift took a dig at West's famed move when she wrote a note to collaborator Ed Sheeran in August, ironically days before the 2013 VMAs aired. 

6. Tom Cruise & Brooke Shields: Cruise attacked Shields in 2005 after she recounted using drugs to fight her post-partum depression in her book Down Came the Rain. Shields followed up with a New York Times op-ed piece where she quipped "I'm going to take a wild guess and say that Mr. Cruise has never suffered from post-partum depression."  The two eventually made up and Shields ironically gave birth the same day as Cruise's wife at the time, Katie Holmes.

7. Kelly Osbourne & Lady Gaga: Though they've actually been feuding since 2009, Osbourne and Gaga's most recent battle didn't last long and ironically started all because of a birthday cake. After Gaga appeared on The X Factor UK and posed with Osbourne's mother Sharon while holding a birthday cake for Kelly, the latter's response was less than grateful. Kelly tweeted "Not to be ungrateful but why would you send me a birthday cake via my MOTHER in a country half a world away? #JustSendItToME #LoveNotWar." She followed that up with a picture of the cake that she captioned "#EatmySh-t #Hypocrisy." She later apologized for the rant, admitting she acted "like a child."

8. Lindsay Lohan & Hilary Duff: The epic battle between the two former teen starlets lasted four years all because both stars wound up dating Aaron Carter at the same time. After Carter dumped Lohan to give it another shot with Duff, it began a feud that involved trash-talking one another until 2007, when they reportedly finally made up.
