Justin Bieber’s “Purpose World Tour” is full of surprises. On Sunday (Mar. 20), the pop heartthrob delivered on that with Big Sean and Chance the Rapper, who came out to lend a hand during the first of three nights at Los Angeles’ Staples Center.

Chance took the stage alongside the Biebs to perform their 2013 collaboration “Confident.” Rocking his trademark White Sox cap, jeans, and a bomber jacket, Chano broke into his Journals verse as the crowd roared.

Then Big Sean came through for “No Pressure.” Sporting a baseball hat, denim jacket, and hoodie, Sean Don delivered his verse off the duo’s Purpose collaboration.

After the show, a grateful Bieber thanked the MCs for blessing the stage.

“Thank you La and thank u @BigSean and @chancetherapper for joining me on stage tonight,” he tweeted.

Beliebers who didn’t catch day 1 of the Staples Center takeover still have two nights left. JB, Post Malone, and Moxie Raia are also set to perform at the L.A. venue tonight and tomorrow.
