Published Dec 06, 2018Bleachers frontman Jack Antonoff hosted his annual Ally Coalition benefit show in New York last night (December 5), and he surprised those in attendance by bringing out his good pal and collaborator Taylor Swift.
She was joined on stage by Hayley Kiyoko, and they performed a duet of Reputation track "Delicate."
Naturally, fans caught the unexpected appearance on camera, and you can watch audience member-shot footage of Swift and Kiyoko below.
Throughout the evening, Lana Del Rey, Mitski, Rostam, Regina Spektor and Antonoff's own Bleachers all performed, as well.
Last year, Antonoff surprised the crowd with a cameo from Lorde. The pair performed a cover of Carly Rae Jepsen's "Run Away with Me."
