13 Nastiest Celebrity Feuds of 2017

This feud has been going on for years now, but it was elevated to dizzying heights in 2017.

"Honestly, it's really like she started it and it's time for her to finish it," said Katy in May during Carpool Karaoke with James Corden.

What followed was a colossal change of heart on Katy's part. In multiple interviews thereafter, Katy was saying that she always loved Taylor.

In a hilarious turn of events, Taylor released all of her music on streaming services the same day Katy released her new album.

This is the feud that keeps on giving.

It's crazy to imagine that NeNe and Kim were once scheduled to star in a joint spin-off of The Real Housewives of Atlanta.

Their feud in 2017 reached new levels of crazy when Kim's daughter, Brielle Biermann claimed there as an insect infestation in NeNe's home.

"@briellebiermann We don't have roaches! If you found 1, u brought it with u or it fell outta yo funky p---y!, said Leakes via Instagram.

"Please know I will get You all the way together when you start f--king wit me and mine!"

NeNe proceeded to call Kim racist, but it backfired in stunning fashion when Kim sought legal counsel.

A third Sex and the City movie was allegedly days away from entering production, but multiple reports swirled, claiming that Cattrall's diva demands for the movie ultimately found it being shelved indefinitely.

Cattrall subsequently chatted to Piers Morgan about her feud with Sarah Jessica Parker and she was not supportive of her former friend at all.

"And this is really where I take to task the people from Sex and the City and specifically Sarah Jessica Parker in that I think she could have been nicer. I don't know what her issue is, I never have."

We'll probably be waiting until a reboot of the series kicks off for a response from Parker.

Caitlyn Jenner released a tell-all memoir that was met with an icy response from the Kardashians.

Caitlyn confirmed in November that the family no longer spoke to her.

Kim was especially mad about the whole thing and opened up about it to Ellen DeGeneres.

"I don't expect her to be honest about my mom now, but it's just so hurtful. Like, I just wish her all the success in the world, but not at our expense."

Drake Bell lashed out at Josh Peck for not inviting him to his wedding.

"When you're not invited to the wedding the message is clear...." he wrote on social media.

In the end, the two men hugged it out at the MTV VMAs and all was right in the world.

Taylor brought her feud with Kim and Kanye back into the spotlight when she had some choice lyrics seemingly aimed at Kanye on "Look What You Made Me Do."

"I don't like your little games / Don't like your tilted stage / The role you made me play / Of the fool, no, I don't like you."

Kim responded months late by reposting the image that included the nude wax figure of Taylor Swift from Kanye's "Famous" video.

Fans were not impressed and the comments of the post were filled with rat emojis.

Fans were shocked when Camilla bid adieu to Fifth Harmony in 2016.

While the two sides had differing opinions about the departure, Fifth Harmony got the last laugh when they thought it would be funny to throw a fifth singer off the stage during a performance at the 2017 MTV VMAs.

Things went nuclear between this duo when Rob lashed out on social media about Chyna cheating on him, being hooked on drugs and being fixated on plastic surgery.

He crossed the line when he shared nude pictures of Chyna.

Chyna fired back with a restraining order against Kardashian, but things slowed down when they reached a custody agreement in private for their daughter.

This feud started in 2016, but it raged on in 2017.

Tyrese was allegedly mad that Dwayne was getting a spin-off of the Fast & Furious film series.

Johnson responded by dragging Gibson's sixth studio album. The feud ended in November when Tyrese took to Instagram to say that he would no longer be mentioning Johnson via social media.

Siggy introduced Margaret to the women, but she was surprised that Margaret had a mouth of her own and did not need to be pushed around.

After various squabbles, the friendship reached breaking point when Siggy called Margaret anti-semitic for making a comment about Hitler.

Counting On star Derick Dillard slammed fellow TLC star Jazz Jennings and the community she represents.

"What an oxymoron... a 'reality' show which follows a non-reality. 'Transgender' is a myth. Gender is not fluid; it's ordained by God," he said via Twitter.

"Every day I experience cyber-bullying, but I keep sharing my story. Today was no different," Jazz responded.

TLC also responded in the best possible way by ousting Derick from Counting On.

Stacy and Clinton worked together for nine years on TLC's What Not to Wear. In 2017, Clinton was shocked to learnt Stacy had blocked him on Twitter.

"It seems juicy but it really wasn't that juicy,"The tea is there ain't no tea," he said during an episode of The Chew.

"I literally don't know whether she blocked me yesterday or a year ago or a month ago or by accident. Well, she could've unblocked me which she hasn't."

"I just wanna say that I've got nothing. I've got no beef with Stacy at all. So, if you ever wanna come back on The Chew, you're welcome to come on The Chew."

Stacy has yet to respond.

Jay-Z responded to Kanye's comments from 2016 this year via his album 4:44.

"Kill Jay-Z," he raps, "But you ain’t the same, this ain’t KumbaYe/ But you got hurt because you think KumbaYe/ You gave him 20 million without thinkin’/ He gave you 20 minutes on stage, fuck was he thinkin’?/ 'Fuck wrong with everybody?' is what you sayin’/ But if everybody’s crazy, you’re the one that’s insane."

Kanye susbequently left TIDAL over a money dispute. So, this one will likely continue to stir up the controversy in 2018.
