The fact that they still have to work together for at least one season of American Idol!
The two feuding AI judges might be doing this for publicity, or they might genuinely dislike one another, but either way they'll have to figure out how to work together.
However, they certainly aren't the first people to dislike their fellow co-workers. Numerous actors, actresses and ball players hated each other and still went out to perform when their numbers were called.
LL Cool J and Jamie Foxx got into a fist fight, Alonzo Mourning and Larry Johnson couldn't stand each other, and hell, even Betty White and Bea Arthur had a little beef behind the scenes at Golden Girls.
So Nicki and Mariah... It's nothing new.
Take a look at some of the most epic beefs between co-stars that the world has ever seen!
The Fresh Prince and Aunt Viv:
You ever wonder why Aunt Viv was dark-skinned one episode, and light-skinned the next? Well that's because Will Smith and Janet Hubert, aka Dark-Skinned Vivian, couldn't stand each other. The two had constant fights off camera and when she got pregnant in real life, Janet claimed she got fired.
Now you know why Lil Nicky was a baby and then suddenly a toddler. It all makes sense now. Not too long ago, Aunt Viv lashed out on Will saying, “He is still an egomaniac and has not grown up. This constant reunion thing will never ever happen in my lifetime unless there is an apology, which he doesn’t know the word.”
Shaq And Kobe:
Just because you win championships together doesn't mean you're friends. Death threats and rap songs left a lot of bad blood between these two. Shaq wrote in his book about how Kobe said he would kill him, and their war of words never knew a boundary. Just take a look at Shaq's rap lyrics: "Ask Kobe how my ass taste." Eww, that's nasty.
Bea Arthur and Betty White:
Who can hate Betty White, right? Well, Bea Arthur couldn't stand Betty's joyful demeanor and once called Betty the world's most disrespectful word. When talking about her Golden Girls co-stars, Bea said, “Betty's a cunt.” Betty herself knew about Bea's disdain for her cheerful ways, and Betty opened up saying, "She was not that fond of me. She found me a pain in the neck sometimes."
Alonzo Mourning and Larry Johnson:
Zo and LJ were once teammates for the expansion Charlotte Hornets, but after a lot of frustration and back and forth talk, things got real when they met in the playoffs on separate teams. Grand MaMa and Zo actually fought during a game, and unfortunately for Mother Nature, the air took a lot of punches, as neither one of the basketball greats actually landed a blow.
Puck Vs. The Real World:
Back in the '90s when MTV put a group of strangers into house, they couldn't have expected that things would blow up the way they did with one guy who called himself Puck. He arrived late because he got arrested, he didn't shower or bathe, and he constantly clashed with a gay roommate. Let's not forget the infamous spitting incident. It made for great TV.
LL Cool J and Jamie Foxx:
LL and Jamie did their thing in the movie Any Given Sunday. But they made major headlines when the two stars clashed on the set of the movie, ending with LL Cool J punching Jamie in the face. Jamie admitted that the altercation actually happened. But these two have since patched up their differences.
Taylor Momsen and Leighton Meester:
It was all good on the set of Gossip Girl until the producers decided to use two songs from Leighton and none from Taylor. You see, both of the stars dabble in music on the side, with Taylor being a bit more edgy and goth.
Nonetheless, the music snub caused a little friction between Taylor and Leighton and the underage bad girl had a lot of resentment towards Ms. Meester. Taylor eventually left the show.
Shannen Doherty vs. Everyone:
Shannen is a beast. She had beef with cast members on all of her shows. On Charmed, her beef with Alyssa Milano made major headlines. Alyssa opened up about the drama saying, "We definitely didn't get along. Shannen and I are very different people, and I think it's almost like a roommate. If you spend that much time with someone and there are differences anyway, you're not always going to get along."
