Big Brother 2025 Cast: Everything We Know So Far

The wait is finally over for fans of the iconic reality show. Big Brother 2025 premieres tonight, Sunday, September 28, 2025, at 9 p.m. on ITV2 and ITVX. A brand-new group of civilian housemates will enter the famous house, kicking off seven weeks of drama, alliances, and unexpected twists.

Hosts AJ Odudu and Will Best return to front the show, promising a season that is “even more mischievous” than before. Long-time narrator Marcus Bentley is also back, ensuring the show retains its signature voiceover style that fans know and love.

Big Brother 2025 Launch Night Details

ITV has confirmed that this year’s run will last for 48 days, making it the longest civilian edition since the show’s revival. The live launch will introduce housemates one by one, with viewers meeting the new cast for the first time during tonight’s episode. No official contestant list was released before air, keeping speculation alive and ensuring maximum surprise.

Episodes will air Sunday through Friday at 9 p.m. for the next seven weeks. Saturdays will remain break nights. The popular after-show, Big Brother: Late & Live, will air nightly at 10:30 p.m., featuring celebrity guests, exclusive unseen clips, and deep dives into the day’s events inside the house.

This year also marks the 25th anniversary of the Big Brother franchise in the UK. Producers have promised fresh twists while keeping the classic format: housemates living together under constant surveillance, competing in tasks, facing public nominations, and trying to avoid eviction until the grand finale.

Celebrity Big Brother 2025 Recap

Earlier this year, the Celebrity Big Brother 2025 edition delivered plenty of drama and star power. Contestants included JoJo Siwa, Patsy Palmer, Donna Preston, Chesney Hawkes, Angellica Bell, Danny Beard, and more. Actor Jack P. Shepherd ultimately won the crown, taking home the title after weeks of challenges and public votes.

The civilian edition now picks up the torch, offering everyday people a chance at reality TV fame and a life-changing prize. Last year, forensic psychologist Ali Bromley made history as the oldest-ever female winner and the first openly lesbian champion of the UK series.

What Fans Can Expect This Season

Producers have teased a “more mischievous than ever” season, suggesting big twists in the first week. Expect unexpected tasks, dramatic evictions, and clever strategic play from housemates aiming to win public support.

The decision to keep the cast secret until the live launch adds excitement, giving viewers a shared first look at the new housemates. Social media buzz is expected to skyrocket as names and personalities are revealed in real time tonight.

Big Brother 2025 is set to bring back everything fans love — intense rivalries, shocking betrayals, and unforgettable personalities — while introducing new elements to celebrate its 25-year legacy.
