Taylor Swift has got some "Bad Blood" with her famous ladyfriends!

The songstress debuted her highly anticipated new music video, "Bad Blood" featuring Kendrick Lamar, which is chock full of her BFFs Zendaya, Gigi Hadid, Karlie Kloss, Selena Gomez, Martha Hunt and Serayah.

The video, directed by Joseph Kahn, was packed with drama, guns, sexy alter egos, boxing babes and a slew of famous famous. While the gals may have been fighting off some bad dudes, they also squared off against each other in the high-octane video.

It's been a big 24 hours for the singing superstar. Last night, the leggy blonde strutted her stuff at Las Vegas' MGM Grand Garden Arena with her video vixens, Zendaya, Martha Hunt, Hailee Steinfeld and Lily Aldridge. Tay Swizz had a big night -- she took home eight Billboard Music awards and went public with new man Calvin Harris. We've caught the two of them canoodling in recent weeks but this was their first red-carpet appearance as a couple. We can't wait to see what song Tay writes about this romp!
