Big Brother 27 Reveals Season's New Houseguests — But Who's The Mysterious 17th Player?

Seventeen new houseguests are about to embark on a summer they'll never forget when Big Brother returns to CBS Thursday, July 10 at 8/7c. And just two days before its supersized 90-minute premiere, we finally have our very first look at who will be entering the front door.

Season 27's cast includes a professional bull rider, event curator, AI consultant (yes, we're getting Ainsley flashbacks, too), an "aura painter" (whatever the heck that is) and a personal trainer, among others. According to the season's official description, these newbies are "stepping into a summer where nothing is as it seems, where every twist rewrites the rules and every turn conceals a hidden agenda."

A 17th mystery player (not pictured below) will also enter the house Thursday, and if you're looking to crack that person's identity, clues are already "hiding in plain sight" on the show's Instagram page.

Last but not least, feedsters can enjoy one last summer weekend of sleep before the live feeds kick on early Monday morning, July 14 at 12:30 am ET. When they're up and running, you can peek in on the hamsters via Paramount+ and Pluto TV.

Check out photos and bios of the new houseguests below, then give us your best guesses as to the mystery player's identity in the comments!
