Celebrity Big Brother is one of the most popular versions of the reality competition series, but it won’t be returning to TV screens any time soon. Celebrity Big Brother is basically the same as the original version of the game, except that it lasts for one month instead of three. There’s also no jury house. Celebrity Big Brother season 1 premiered in February 2018, with Marissa Jaret Winokur taking home the grand prize. Season 2 debuted in January 2019, with Tamar Braxton being crowned the champion, while season 3 aired in February 2022, with Miesha Tate being voted the winner.
