‘Big Brother’ Returns for Season 27 — Meet the New Cast

Season 27 of "Big Brother" kicks off with a twist no one saw coming. Sixteen strangers are entering the house, but one of them might not be who they claim to be.

"Big Brother" returns this week for its 27th season. CBS confirmed the official theme as "Big Brother: A Summer of Mystery" on Wednesday, July 2. This season promises more than just competitions and alliances. The network teased an interesting lineup filled with surprises.

This includes a masked visitor, a secret accomplice, and a mystery houseguest. The identity of the mystery guest will remain undisclosed for the time being. CBS hinted that fans of the reality show can expect twists designed to keep both houseguests and audiences guessing.

Sixteen new houseguests are stepping into the "Big Brother" house, each bringing their own strategy, background, and ambition. Ashley Hollis, a New York attorney and lifelong fan, isn't holding back. "I'm ready to get the blood on my hands," she said. Adrian Rocha, a carpenter from San Antonio, said he is excited to be part of the game.

As for Amy Bingham, an insurance agent from Stockton, she is confident she has what it takes. Ava Pearl, an NYC-based art instructor, said winning is personal. "I need the money the most."

Cast member Clifton Williams, a podcast host from Charlotte, noted that he is entering as "Captain Will" and promises to shake things up. Twenty-three-year-old Isaiah "Zae" Frederich, who hails from Utah, noted that his strategy is to dominate in every way — physically, socially, and mentally.

Jimmy Heagerty, a D.C.-based strategy consultant, believes his background gives him the edge, while Katherine Woodman, a fine dining server from South Carolina, brings quiet poise. Keanu Soto, a trainer from Texas, relies on strength, while Kelley Jorgensen, a web designer from South Dakota, comes armed with tech smarts.

Lauren Domingue, a bridal consultant from Louisiana, brings charm and drive. Mickey Lee, an event curator from Atlanta, aims to make a bold impression. Morgan Pope, a model and gamer from L.A., blends looks with gameplay.

Rylie Jeffries, a pro bull rider from Oklahoma, is ready to compete. Vince Panaro, unemployed and from L.A., is here to rewrite his story. Zach Cornell, a marketing manager from Atlanta, says he's always thinking two steps ahead. With a diverse cast and high-stakes theme, Season 27 is set to deliver an unpredictable summer.
