After watching all of Taylor Swift's "Bad Blood" behind-the-scenes videos, I have come to the conclusion that it was the most fun had... ever.

The singer has been posting a ton of BTS moments of her besties from the set to celebrate the song's success and the video's VMA nomination for Video of The Year.

So here is a round-up of all the 15-second Instagram videos, including the latest, which shows what happened after Taylor and Selena Gomez faced off in the video's final scene.

Selena Gomez as 'Arsyn' AKA The Villain

While these two are besties in real life, they had to pretend they had some serious bad blood on set. After filming the epic final scene, they couldn't stay mad for long, laughing and hugging it out once the cameras stopped rolling.

Ellie Goulding as 'Destructa X'

Here's some advice: don't mess with a girl holding a bazooka.

Zendaya as 'Cut-Throat'

Hitting a bulls-eye every time is what Cut-Throat does best, which is how Taylor helped Zendaya come up with her name.

Mariska Hargitay as 'Justice'

It's only fitting that the woman whose "Law & Order: Special Victims Unit" character is the namesake of Taylor's cat, Olivia Benson, serves as Taylor's mentor in the video.

Ellen Pompeo as 'Luna'

If Mariska Hargitay was appearing in then video, then you knew Ellen Pompeo would be as well. Her "Grey's Anatomy" character, Meredith Grey, lends her name to Taylor's other cat. Ellen and Mariska team up to teach Taylor how to be a badass spy.

Martha Hunt as 'Home Slice'

Who knew that Martha and Taylor were skilled sword fighters and basically twins?

Hailee Steinfeld as 'Trinity'

Three times the fun.

Jessica Alba as 'Domino'

Jessica, who was on set the first day of the shoot, is a badass motorcycle expert who is teaching Taylor everything she knows.

Hayley Williams as 'The Crimson Curse'

Hayley Williams is not only is an amazing vocalist, but apparently she's a gymnast as well. I mean, she totally nailed that flip.

Karlie Kloss as 'Knockout'

You don't usually find yourself in a boxing ring with your BFF, but when you do, you don't "mess around." BTW, this is super intense.

Seraya as 'Dilemma'

The "Empire" star has a mean left punch that can literally break through a wall. Don't mess with her.

Lily Aldridge as 'Frostbyte'

Don't cross Frostbyte because that girl has a weapon to kill. Luckily that wasn't thrown during the shoot, but we do see Taylor doing some sick backflips.
