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.”

CBS revealed the much-awaited Big Brother Season 27 housemates in their recent Instagram post, shared on July 8, 2025. It features a total of 16 housemates.

The new season of the hit reality competition series "Big Brother" includes new elements including the introduction of a mysterious masked visitor with a secret accomplice and an unknown houseguest to be revealed sometime during the season.

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.

I'm a Big Brother fan, and like Tucker from BB26, I also "really like puzzles!" Especially crossword puzzles. So naturally, it's my idea of a good time to put together a crossword puzzle that's solely focused on Big Brother (U.S. edition).

I never expected that person. And I was very excited because, in my opinion, getting that person is epic,” the host said.
