Big Brother season 27 premiered on July 10 with a 90-minute episode. During the premiere, season 13 winner Rachel Reilly was unmasked as the "mystery Houseguest" who would be joining the contestants in Hotel Mystère. In July 2025, Chen Moonves told Entertainment Weekly that "people should be afraid of [Reilly] and of getting in her crosshairs."

New episodes of “Big Brother” season 27 air every Wednesday, Thursday, and Sunday at 8 p.m. ET on CBS. Stream the series with Fubo, DirecTV, and Paramount+ (free trials available).

Vince Panaro is the first HoH of season 27. Only four people got to compete in the first HoH competition: Jimmy Heagerty, who won a separate comp during the premiere, and the three people he selected to go up up against him, Vince, Ashley Hollis, and Adrian Rocha.

You can watch new episodes of Big Brother live on CBS, CBS.com, or with an active subscription to Paramount+ Premium, which is currently available for only $0.99/month for your first two months ($12.99/month after). However, you’d better hurry, as the offer ends on July 13.

Big Brother follows a group of people living together in a house outfitted with more than 100 cameras and 100 microphones, recording their every move 24 hours a day. Each week, someone will be voted out of the house, with the last remaining Houseguest receiving the grand prize of $750,000.

"Big Brother" is set to premiere this week. For Season 27 of the hit reality competition series, the official theme will be "Big Brother: A Summer of Mystery," CBS confirmed Wednesday, July 2.

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.

With Season 27 of Big Brother fast approaching, a few contestants from recent seasons of the reality competition show had advice for the new batch of houseguests. Surprisingly, it had nothing to do with the game.
