Taylor Swift's "Bad Blood" Breaks Record

It's hardly a shock, but Taylor Swift's new guest star-laden video for her single "Bad Blood" is huge.

The clip -- whose cameos include Lena Dunham, Hailee Steinfeld, Jessica Alba, Cindy Crawford, Selena Gomez, Lily Aldridge, Zendaya, Gigi Hadid, Paramore's Hayley Williams, Serayah McNeill, Ellie Goulding, Karlie Kloss, Mariska Hagitay, Carla Delevingne, Martha Hunt and Kendrick Lamar -- broke a Vevo record wtih some 20.1 million views during its first 24 hours online.

When the news was released Swift tweeted: "FREAKING OUT RIGHT NOW. YOU BROKE THE VEVO RECORD. THANK YOU."

In subsequent tweets she also gave props to the video's guests, saying that, "I'll never be able to thank you enough."

Swift has said "Bad Blood" is about another female artist who tried to sabotage one of her tours by hiring away people who usually worked for Swift; some have named Katy Perry as the subject, but Swift has not revealed who it is. Certainly, however, it’s another example of how Swift`s "1989" album has veered away from songs about former boyfriends: "It's pretty, y'know...I think 'boycentric' is a word that people sometimes use for it, but it's not a very boycentric album 'cause that hasn't been the focus, really, for me. In the last few years it's not been a priority. So if there's a song about relationships it's reflecting back on an old relationship and what I learned from it or something like that. But...I don't think anyone from my past or in my life will be really upset by this album."

Swift is currently on the North American leg of her 1989 World Tour.
