SPIN’s been a fan of 18-year-old Swedish pop phenomenon Zara Larsson for a while now, but it’s only recently that her bold collaboration with MNEK, “Never Forget You,” blew up in a big way. Last night, Jimmy Fallon had the artist behind the No. 1 dance song in the country come to his Tonight Show for a thrilling performance of her big hit. Larsson looks and sounds like she belongs in front of a big audience, so here’s hoping for more great things to come (and #JusticeForLushLife). Check her Tonight Show gig out below.
