kicked off a new season on Wednesday, and host Julie Chen Moonves had some big twists and turns for the 16 new houseguests who moved into the household.The show began by introducing the new houseguests, four at a time, to the desert festival-themed house, and the Big Brother Fest competition.The guests each got a special pass, which directed them to one of three Big Brother Festival stations — the Porta Potty area, the Merch Stand and the Piercing Station. With five houseguests in each location, that only left one -- Joe 'Pooch' Pucciarelli — to sit in a golden throne as the so-called Backstage Boss.Before revealing what that would actually entail, the three groups of five houseguests all had to face off in different challenges.
