Lorde covers Robyn's "Hang With Me" with Jack Antonoff

The performance took place during last night's third annual Ally Coalition Talent Show - a benefit put on by Antonoff supporting homeless LGBTQ youth. Although the lineup was pretty star-studded already, Lorde's appearance was a special surprise.

Charli XCX, Carly Rae Jepsen, Bleachers, Lauren Mayberry of CHVRCHES, Hasan Minhaj, Lena Dunham, Mike Birbiglia, Jordan Carlos, and fun.'s Andrew Dost all also performed on the night. Mayberry performed an acoustic cover of Katy Perry's "Firework".

Antonoff led all the performers through a rendition of "Go Your Own Way" by Fleetwood Mac towards the end.
