Big Brother host Julie Chen Moonves has an opinion on the state of the Big Brother 27 house - and it's probably not what fans are expecting. "I think Kelley [Jorgensen] has become the dark horse," Chen Moonves, 55, told Entertainment Weekly in an interview published Friday, August 1. "As long as the BB Block Buster exists, she can keep this going. She is good at comps and focused." Kelley, 29, has caught the ire of Big Brother fans for volunteering to be nominated for eviction each week of the game so far.
