"Yo, Taylor, I'm really happy for you. Imma let you finish, but Beyoncé had one of the best videos of all time!"
Who can forget Kanye West's now infamous words as he crashed Swift's award speech at the 2009 MTV VMAs? West's intrusion ignited one of the most famous celebrity feuds in recent years.
Following the incident, West apologized for his comments and everything seemed to be over. Swift even presented the rapper with the MTV Video Vanguard Award at the VMAs in 2015.
The "Famous" video was infamously the cause of the re-falling out between Taylor and Kanye, after she claimed she never gave permission for West to use her name in lyrics expressing his belief they might sleep together one day. A secretly recorded video subsequently posted by Kanye's wife Kim Kardashian seemed to contradict this narrative, as it showed the two musicians discussing the same and Kanye clearly asking for her blessing.
Swift later claimed her point of contention was being referred to as a "bitch" in the song; nevertheless the episode earned her the snake reputation, which she in turned owned and used it for the theme of her last album and tour.
The two pop stars used to be friends way back in 2009. However, their friendship was said to have hit a roadblock when Perry became close to John Mayer, who was rumored to have previously dated Swift. The "Gravity" singer also dueted with Swift on her "Fearless" tour.
The drama escalated when backup dancers switched from Perry's tour to Swift's and then back again to Perry. The "Firework" songstress gave her side of the story regarding the dancer debacle on "The Late Late Show's" "Carpool Karaoke" in 2017.
Both Perry and Swift are each believed to have written a song about their rival at the time: Perry's 2017 hit "Swish Swish" and Swift's song "Bad Blood" in 2014.
Luckily, it seems like the bad blood is now gone for good. Last month, the ladies suggested their feud was over when Perry shared a post on Instagram last month.
The "American Idol" judge's post's consisted a photo of a plate of what looked like homemade chocolate chip cookies with the words "peace at last" written in red icing on top of the plate. Perry captioned the post, "feels good @taylorswift" along with a heart emoji and tagged the "ME!" singer in the photo as well.
Just a few days later, Perry made a cameo in Swift's music video for her song "You Need to Calm Down."
It's hard to believe Tina Fey and Amy Poehler could have a feud with anyone, however, that changed when the "Saturday Night Live" alums poked fun at Swift's love life and history of celebrity boyfriends during their 2013 Golden Globes monologue.
In response, Swift hit back with a Madeleine Albright quote: "There's a special place in hell for women who don't help other women."
Fey later responded by telling ET that it was a "shame she didn't take [the joke] in the crazy-aunt spirit in which it was intended."
"I did not see that one coming," she added. "It was a joke. It was a lighthearted joke."
Nicki Minaj and Swift had a short, but notable feud. Back in 2015, Minaj and Swift ignited some beef on Twitter after the rapper took to the social media app to voice her frustrations about not being nominated for the MTV VMAs that year.
"If your video celebrates women with very slim bodies, you will be nominated for vid of the year."
Although Minaj wasn't referring to Swift, the "Blank Space" singer hit back at the "Monster" rapper and accused her of trying to pit female artists against one another. Minaj then clarified what she meant.
"Huh? U must not be reading my tweets," she wrote. "Didn't say a word about u. I love u just as much. But u should speak on this."
Swift later apologized on Twitter and all seemed to be cleared up. Swift even joined Minaj onstage during the VMAs.
Swift's most recent feud involves music manager Scooter Braun, who acquired the rights to her old music after he purchased the singer's former music catalog from her old label, Big Machine Label for over $300 million.
The "ME!" singer, who said she wasn't informed of Braun's purchase before it went public, took to Tumblr earlier this week to slam Braun and claimed he's been bullying her for years.
"Scooter has stripped me of my life's work, that I wasn't given an opportunity to buy," Swift wrote. "Essentially, my musical legacy is about to lie in the hands of someone who tried to dismantle it."
"I learned about Scooter Braun's purchase of my masters as it was announced to the world," she later added. "All I could think about was the incessant, manipulative bullying I've received at his hands for years."
The story caught the eyes of both Swifties and celebrities alike, all who voiced their opinions on the subject. While some artists including Alessia Cara, Halsey and Brendon Urie took Swift's side, Braun's longtime client, Justin Bieber, sided with his manager and consequently ignited his own feud with Swift.
