Justin Bieber began a three-night takeover at Los Angeles' Staples Center on Sunday (March 20) as part of his Purpose World Tour—and he kicked things off in a major way. The singer brought along previous collaborators Big Sean and Chance The Rapper as his special guests.
The Canadian popstar (who amped up his cool cred by rocking a 2Pac shirt) and Sean Don came together for their slinky Purpose track "No Pressure," while Chance The Rapper rushed on the stage for his bouncy 2013 "Confident" collaboration with Bieber.
Naturally, the frenetic screams from the teen Beliebers took over the arena as the rappers made their surprise appearances. There are two more nights left for Bieber's L.A. concert bash, so we'll keep our eyes peeled for whom he plans to bring out next!
