Expect the unexpected.
“Big Brother” fans have been hearing host Julie Chen Moonves recite that phrase about the CBS hit reality TV competition show for years. And as the show hits 25 years in 2025, that “Big Brother” classic slogan is more appropriate than ever for Season 27, which premieres on July 10.
“We’re celebrating 25 years of Big Brother with the biggest season yet,” Chen Moonves promised in a preview video released on the official Instagram account of “Big Brother.”
The “Big Brother” houseguests will enter a Hotel Mystère house and there promises to be a bevy of twists beginning during the premiere, including a masked visitor and a secret accomplice, plus a mystery houseguest.
What won’t change are the 110-plus cameras and microphones that will follow and capture the houseguests’ every move as players navigate social and strategic dynamics throughout the next three months in attempt to win “Big Brother.”

A player with a Wisconsin connection is part of the storied history of “Big Brother.”
Xavier Prather, then a Milwaukee attorney who got his law degree at Marquette University, won season 23. He was the first Black winner in “Big Brother” history after capturing every vote. Prather also became the first winner to take home $750,000 (previous winners won $500,000). Prather returned to the “Big Brother” house to participate in a holiday-themed spindoff a couple years ago where he advanced to the finale.

See inside the ‘Big Brother’ season 27 house
Chen Moonves gave fans a sneek peak inside the “Big Brother” house, which is located in the CBS Studios Center in Los Angeles.
“This season ‘Big Brother’ house is what I like to call, not a house but a hotel,” she said.
The house includes a “creepy reception desk,” and a return of bunk beds for the first time since season 1.
“They’re coming back,” Chen Moonves said.
There are also decorations that lend itself to your favorite mystery, plus two lounges, a wine bar, minus the wine, and a venom bar.
But there is no venom, Chen Moonves said.
“We didn’t have to supply the venom bar with venom,” she said. That’s because “there’s plenty within the houseguests,” who “bring the venom.”
Who won ‘Big Brother’ last year?
Chelsie Baham, a 28-year-old nonprofit director, won “Big Brother” season 26 in the summer of 2024.
