Justin Bieber's "Purpose" world tour is off to a fast start as the Canadian singer is currently taking over Los Angeles for three shows at Staples Center. For the first show last night, Bieber made sure he left his mark with the fans, as he brought out Chance the Rapper and Big Sean at different points during the set, which sent the crowd into an absolute frenzy. With Chance, Bieber performed the banger "Confident" before Big Sean eventually joined him on stage to run through the Purpose cut "No Pressure." Bieber later tweeted his thanks to both Chance and Sean for joining him on stage, and it really makes you wonder what kind of surprises he has in store for the rest of the tour. You can check out the footage above and below, and peep the rest of the dates for the tour right here.
