She used her alias again for the cover of her song “Look What You Made Me Do” which was featured on the TV series Killing Eve. Taylor talked about the cover and mentioned that the song was sung by a band named Jack Leopards & The Dolphin Club. In reality, Jack Leopards & The Dolphin Club does not exist. Swifties soon started speculating that the song was covered by none other than Taylor’s brother and actor Austin Kingsley Swift. Fans also speculated that Taylor used Nils Sjöberg as a band member to not let Scooter Braun earn profits from the cover.
At the time, Braun still owned Taylor’s master recordings for her six albums under Big Machine Records and hence would have received the song’s royalties. By using the pseudonym, Taylor made sure that the royalties from the song were diverted towards her.
