The Grammy winner, 29, performed her hits including “Welcome to New York” and also “Shake It Off” to a celeb-studded crowd. While she did not directly address the feud between herself and Justin Bieber‘s manager Scooter Braun and her former record label Big Machine, she sent fans into a spin when she emphasized the “Shake It Off” line “liars and the dirty, dirty cheats of the world.” Her audience also had her back with fans handing out hearts that read, “Hold this PINK heart against your flashlight the moment Taylor Swift finishes performing her first song. #WeStandWithTaylor Follow @theSwiftie911” Also in the audience supporting her were Gigi Hadid and Ashley Avignone, along with Justin Theroux, who took videos of Swift’s set. Other performers at the event — hosted by Jane Lynch — included Dua Lipa, SZA and Becky G. Evan Agostini/Invision/AP/Shutterstock Taylor Swift.

Braun has not commented on the situation or the singer’s claims about him. Last week, the Swift doubled down on accusations she made via her post that she “wasn’t given an opportunity to buy” her “life’s work.” Taylor Swift.

A source previously told Variety that Swift had to sign a deal that would bind her to Big Machine or its new owner for another 10 years in order to buy her masters or the label. Neither Swift nor Borchetta have commented further about their failed contract negotiations — including the specifics of any offers that were made from either side. However, hours after Swift said she was “grossed out” by Braun’s acquisition of Big Machine Label Group and her catalog, Borchetta did respond with his own lengthy statement on the label’s website, essentially accusing Swift of bending the truth.
