This summer, as the Weeknd-starring HBO show The Idol rolls out from week to week, the Weeknd himself is on a stadium tour that will be making its way around Europe until August. This weekend, he was in Stockholm, performing at the Tele2 Arena. Last night, he brought out his Idol co-star Suzanna Son, last seen in Red Rocket, and they performed “Family,” a song that debuted in last week’s episode.
