There’s no telling who you’ll see at Coachella this year. In addition to Beyoncé, Jay Z, Gwen Stefani, and Puff Daddy, The Biebs (Justin Bieber) also made a surprise appearance at the festival on Sunday. The Canadian pop superstar joined Chicago’s Chance the Rapper during his afternoon set on the main stage.

Wearing a bucket hat, a black T-shirt, and bandana with shades, Biebervelli performed “Confident” with the Chicago MC and danced on stage during the end of his set.
