"South Park" Season 27 first airs on Wednesday, July 23, at 10 p.m. ET/PT. It won't be the last season, either. In 2021 Parker and Trey signed a reported $900M deal with Comedy Central to extend South Park to Season 30, taking the show up to 2027.

After much anticipation, Big Brother Season 27 revealed the mystery houseguest. Former contestant and winner of the thirteenth season, Rachel Reilly, joined the CBS show as the mystery houseguest.

Before the season 27 premiere, many fans speculated that the mystery houseguest could be anyone from Celebrity Big Brother UK star JoJo Siwa to a Big Brother newcomer like Tom Sandoval from Vanderpump Rules. Viewers even hypothesized that this season, the host herself, Julie Chen Moonves, would join the cast as a contestant.
