On Wednesday (December 5), Jack Antonoff hosted his annual Talent Show to raise money for at-risk LGBTQ youth. Lana Del Rey, Regina Spektor, Bleachers, and Rostam took the stage at the concert now its fifth year, but one artist not previously announced made a special appearance—Taylor Swift.

Swift joined “lesbian Jesus” Hayley Kiyoko for a stripped-down version of “Delicate” from Swift’s Reputation.

Founded by Antonoff and his sister Rachel who hosted the event, the nonprofit Ally Coalition raises funds, creates awareness, and advocates for at-risk LGBTQ youth through various events held throughout the year.

In January, Lorde joined Antonoff for a performance of Carly Rae Jepsen’s “Run Away With Me” for the fourth Talent Show installment.
