Image Credit: CBS Big Brother season 27 is approaching its dramatic season 27 finale this month. Premiering on July 10, 2025, this "Summer of Mystery" edition of the long-running CBS reality TV series introduced a "Hotel Mystère" theme in addition to the returning BB Block Buster twist. In a house designed as a suspense-packed hotel, the cast has been through quite a ride so far. So, when will it end? The show shook things up during week 8 when a new HOH wasn't revealed. Not only that, but Vince "Vinny" Panaro and Morgan Pope's evolving relationship raised a lot of eyebrows in the audience.
