Taylor won 9 Billboard Music Awards Sunday night. But the highlight was the unveiling of her new music video, "Bad Blood."

There are so many celebrities in this video I can't name them all. I saw Lena Dunham, Cindy Crawford, Mariska Hargitay, Jessica Alba, Selena Gomez....OK...it's a long list.

"Bad Blood" is kind of a mix between "Kill Bill" and "The Matrix."

Don't take my word for it.  Check it out below.  Let us know what you think of the video in the comments down below.
