The premiere of Big Brother Season 27 is just days away, but that's not soon enough for some. The house and theme were revealed, as well as the existence of a mystery 17th Houseguest. CBS decided to tease fans just a bit more by dropping a five-second promo featuring five of the new contestants.

Julie Chen Moonves says she’ll stay with Big Brother as long as Jeff Probst and Phil Keoghan continue hosting their shows on CBS

The “Big Brother” 27 live feeds won’t begin until Sunday, July 13, at 12:30 a.m. ET, which is three full days after the premiere. It’s likely that the feeds are being delayed to preserve the mystery houseguest’s identity, which suggests that we won’t know who they are until the July 13 episode of “Big Brother.”

She's referring, of course, to fellow longtime CBS reality hosts Jeff Probst ( Survivor ), who also started in 2000, and Phil Keoghan ( The Amazing Race ), who began in 2001. The way Chen Moonves sees it, the three are tied at the hip, and she doesn’t want to be the first one to cut the rope.

CBS’s Big Brother returns with a new season packed with twists. Among the contestants: Amy Bingham, an insurance agent from Stockton. Here's how she plans to win.
