Last night The Ally Coalition held their third annual talent show at New York City's Webster Hall. The charity event brings stars together to perform as they work to raise money to support homeless LGBTQ youth in NYC. For this year's event, the lineup included performances from Lorde, Chvrches' Lauren Mayberry, Carly Rae Jepsen, Bleachers, and more.

In usual talent show fashion, the stars on the lineup took the stage to show off their skills by performing covers of some well-known songs by other artists. During the show, Lauren Mayberry of Chvrches took the stage to share a performance of Katy Perry's 2010 radio hit "Firework" while Carly Rae Jepsen joined Jack Antonoff (of Fun. and Bleachers) to perform "Shadow."

While fans continue to wait for her to release her long-awaited sophomore album, Lorde surprised the audience with an unexpected guest appearance at last night's event. She took the stage next to Antonoff to sing a down-tempo cover of Robyn's 2010 single "Hang With Me."
