Last night [Monday, March 21] Justin Bieber kicked off the first of three nights worth of shows in Los Angeles with an unexpected performance from Chance The Rapper during his Purpose tour.

Performing “Confident” together (which features on Justin’s 2013 album, Journals) Chance was the last surprise guest to accompany the Canadian singer on stage.

The crowd, who seemed pleased to have Chance join the singer, was earlier surprised by Big Sean who performed a live rendition of “No Pressure” with Justin.

Justin Bieber ends his tour New York City’s Madison Square Garden on July 18.
