Watch: Zara Larsson Reveals Who She's Calling After Midnight

Zara Larsson revealed who she's calling after midnight when she was backstage at the 2026 iHeartRadio Music Festival presented by Capital One.

Larsson, 28, helped kick off the first night of the two-night, genre-spanning event with an energetic set on Friday night (September 18). She was one of several acts to take the T-Mobile Arena stage in Las Vegas, Nevada. While she signed autographs backstage, iHeartRadio asked the singer-songwriter, "who are you calling after midnight?"

Larsson thought for a moment, and then quickly shared her answer. Watch that moment here.
