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.
