In the final scene of the video, one of the Taylor's says to the other: "There she goes playing the victim again." Another responds in kind, "Shut up!"
Swift, 27, has been teasing and hinting all week on her social media accounts that new music was coming.
The music video caused headlines before it was even released thanks to those images.
Beyoncé's fans cried foul, saying that one shot, in which Swift is wearing all black inside a Victorian-style home, felt similar to Beyoncé's "Formation" video, in which she at one point also wears all black in a plantation-style home.
Kahn defended the music video on Twitter Friday, writing: "I've worked with Beyoncé a few times. She's an amazing person. The #LWYMMDvideo is not in her art space. Love and respect to Bey."
"Look What You Made Me Do" is the first single from the Grammy Award-winning artist's album "Reputation," out Nov. 10.
