These 16 houseguests and one reality television legend moved into the famous “Big Brother” house for a summer filled with competitions, alliances and back stabbing.

Big Brother season 27 premiered on July 10 with a 90-minute episode. During the premiere, season 13 winner Rachel Reilly was unmasked as the "mystery Houseguest" who would be joining the contestants in Hotel Mystère. In July 2025, Chen Moonves told Entertainment Weekly that "people should be afraid of [Reilly] and of getting in her crosshairs."

Rachel Reilly isn’t the only returning Big Brother houseguest who will be gracing our TV screens this season. CBS announced Tuesday that former winners Derrick Levasseur (BB16) and Taylor Hale (BB24) will join together to host Big Brother: Unlocked,

Law & Order: Special Victims Unit is one of NBC's longest-running dramas, as it premiered in 1999 and features more than 500 episodes. The police procedural will return with Season 27 this fall.

Before NBC renewed Law & Order: SVU for season 27, multiple outlets confirmed in May 2025 that Octavio Pisano and Juliana Martinez, who portray Detective Joe Velasco and Detective Kate Silva, respectively, were leaving at the end of the current season after Michele Fazekas was announced as the series’ first female showrunner.

Kaycee’s appearance on Big Brother 27 is a quintessential example of “expect the unexpected.” Specifically because the winner proved to be victorious once more, getting the much-needed Veto for Keanu. It’s certainly a reaction that will have the personal trainer and dungeon master yelling, “Let’s go!” in exaltation.
