Ever since Mariah Carey uttered her famous "I don't know her," line in reference to Jennifer Lopez, the internet has been abuzz with speculations that there was some major shade being thrown by both sides. According to Yahoo, there is definitely a feud going on between Carey and Lopez and it shows no signs of stopping.

Since the Carey/Lopez feud know no bounds, it has spilled over into other celebs' lives. After a meme that stated, "When you order online vs. when it arrives," (putting Mariah Carey as the expectation and Ariana Grande as the reality), Demi Lovato rushed to Grande's defense in a post that has since been deleted but was screen grabbed by thecelebriteanews on Instagram.

In addition to defending Grande, Lovato also took the opportunity to throw some extra shade at Carey for her "nasty comments" regarding Lopez. According to Billboard, Lovato didn't back down, "This is why I posted what I did. Jen keeps it classy but I'm not afraid to say sh*t. The woman is mean for no reason. Extremely talented? Yes. Superhuman? Possibly. Unnecessarily rude? Absolutely."

Though some of Mariah Carey's spats with other stars have been a bit subtle, there was nothing ambiguous about the way Carey and Nicki Minaj feel towards each other. According to MTV, the Carey/Minaj beef all started when the stars both landed gigs as judges on American Idol. In an Us Weekly article, Carey elaborated on her Idol experience with Minaj saying, "It was like going to work every day in hell with Satan." Not to be outdone, Minaj refused to play nice with Carey. MTV reported that Minaj had a few choice words to say about Carey, "I'm not f***ing putting up with her f***ing highness." At least these two are open and honest with their feelings, right?

Places like Refinery29 have been talking about Miley Cyrus and cultural appropriation for awhile now, but things recently came to a rolling boil. It all started with the 2015 VMAs and Cyrus tweeting a criticism of Nicki Minaj. Understandably Minaj was none too thrilled with both the shade and the appropriation. In an interview in People, Minaj stated, "you're in videos with black men, and you're bringing out black women on your stages, but you don't want to know how black women feel about something that's so important?" Clearly the two are at odds about how racial issues are handled.

Though Taylor Swift is no stranger to airing her grievances through music, rarely does she name who her lyrics are directed at explicitly. Yet it doesn't take a detective to piece together the clues that Taylor Swift and Katy Perry have some "bad blood." According to BuzzFeed, the Swift and Perry feud has been going on for years and their tweets indicate there's no end in sight.

Everyone remembers when Kanye West interrupted Taylor Swift's acceptance speech, but the hatred goes even deeper than that. In a recent interview with GQ, West's Kim Kardashian called out Taylor Swift for denying she agreed to West referring to her in an unsavory way in his song "Famous." Now, according to CNN, Swift's team released a statement in response to Kardashian's claims, "Taylor cannot understand why Kanye West, and now Kim Kardashian, will not just leave her alone."

Katy Perry's ex Diplo tweeted, "Someone should make a kickstarter to get taylor swift a booty." He also compared Taylor Swift fans to the North Korean Army. Doesn't exactly sound like these two will be best buds anytime soon.

Azalea Banks accused Zayn Malik of stealing material and being a racist . Malik and Banks exchanged a series of tweets and, despite an apology from Banks, they are still not on good terms.

When Skai Jackson defended Zayn Malik against Azalea Bank's racist and homophobic tweets, Banks turned her hatred towards Jackson. In a now-deleted tweet, Banks wrote, "and you need to grow some hips and start ur menses. stay in a child's place," to which Jackson tweeted back, "when a no hip having 14-year-old has more class than you. Worry about your career. Get one." Burn.

According to Us Weekly, Chelsea Handler called Angelina Jolie a "demon," a "homewrecker," and that, "she seems like a woman you'd want to avoid." InTouch Weekly pointed out that Jolie's lack of a response actually speaks volumes because her silence appears to be a snub directed towards Handler.

According to Bustle, Kim Kardashian and Paris Hilton aren't friendly due to years of drama. Though they've mostly been quiet about each other, they certainly aren't BFFs like they used to be.

You may have thought that the '00s feud between Paris Hilton and Lindsay Lohan was old news, but fires were reignited when The New York Post wrote that Hilton's brother was attacked by a man allegedly at the command of Lohan because the Hiltons were purportedly throwing shade at Lohan.

It began when Lindsay Lohan tweeted, "Why did I get put in jail and a Nickelodeon star has had NO punishment(s) so far?" Many speculated this was directed at Amanda Bynes. Not to be outdone, Bynes has also direct some shade towards Lohan, according to Us Weekly.

In an interview with TMZ, Tara Reid claimed that she and Lindsay Lohan really do not like each other. It seems that alcohol and too much partying might be a factor, according to The Huffington Post.

Though Christina Aguilera has stayed relatively mum on the situation, according to People, Kelly Osbourne has notoriously called Aguilera "fat" and displays a great distaste for the singer.

According to Us Weekly, this feud stems from Justin Bieber flirting with Orlando Bloom's ex, Miranda Kerr, and Bloom being spotted with Bieber's ex, Selena Gomez. Bloom even threw a punch at Bieber which only fueled their feud even more.

The Black Keys' drummer, Patrick Carney, openly hates Justin Bieber, according to an interview in Rolling Stone. Apparently the feeling is mutual since Bieber tweeted, "The Black Keys drummer should be slapped around haha."

There's no subtext when Seth Rogen tweeted, "All jokes aside, Justin Bieber is a piece of sh*t," after a brief meeting with the singer. In response Bieber tweeted, "Seth Rogan sorry I didnt bow down when I asked 2 meet u," implying it was Rogen who was acting in poor taste.

In an interview with TV Guide, Anthony Bourdain called Paula Deen, "the worst, most dangerous person to America." Firing back in an interview with Page Six, Paula Deen said, "Anthony Bourdain needs to get a life."

In a radio interview with "The Breakfast Club" on Power 105.1, Chris Brown dissed Drake and even made disparaging remarks about his alleged interest in ex-girlfriend, Rihanna. With some really misogynistic statements, Drake shot back at Brown, according to Billboard.

This feud is likely traced back to Meek Mill's tweet, "Stop comparing drake to me too.... He don't write his own raps! That's why he ain't tweet my album because we found out!" Rolling Stone noted that Drake fired back at Meek Mill with lyrics like, "I let the diss record drop, you were standing right below me, n***a."

According to MTV, the feud began when Future had a seemingly negative review of Drake's music, "Drake made an album that is full of hits but it doesn’t grab you." In what surely wasn't a coincidence, Future was dropped from Drake's tour resulting in a lawsuit where Future feels he is owed 1.5 million dollars, according to Page Six.

When Glee creator, Ryan Murphy wanted to use Kings of Leon's song, "Use Somebody," and they didn't agree, things headed south quickly. Following the rejection, Murphy called Kings of Leon out in an interview with The Hollywood Reporter, "They’re self-centered assholes.” Kings of Leon's Nathan Followhill, in a now-deleted tweet, wrote, "Dear Ryan Murphy, let it go, See a therapist, get a manicure, buy a new bra." To which Murphy responded in The Hollywood Reporter, "F**k you, Kings of Leon." Alright, then.
