Justin Bieber performed in Los Angeles on Sunday night for the first of three local concerts of his "Purpose" world tour, which will travel around the globe until the end of November. The pop idol hit the stage after opening acts by soulful singer Moxie Raia and rapper Post Malone. Beliebers filled the Staples Center in Downtown LA to capacity and squeals of joy filled the giant auditorium at every hair flip and doe-eyed pout. Bummed you missed out on the show?
