Off the Block with Ross and Marissa (often shortened to just Off the Block)[1] is a reality aftershow and spin-off of Big Brother hosted by Ross Mathews and Marissa Jaret Winokur who were both HouseGuests on the first season of Celebrity Big Brother.

[3] The first aftershow attempted by CBS began in 2004 with House Calls: The Big Brother Talk Show[4] The series primarily featured a discussion about events occurring in the Big Brother house.

[9] Ahead of Big Brother 20 it was announced by Julie Chen on Twitter that Celebrity Big Brother 1 runner-up and winner Ross Mathews and Marissa Jaret Winokur would be filling in the gap left by Schroeder with a new show called Off the Block.

[10] Due to the format of Big Brother, beginning with episode 7, the hosts are required to keep certain aspects of the parent series confidential from the evicted HouseGuest in an effort to keep their Jury vote unbiased.

[11] The show airs on Fridays the day after live eviction episodes of Big Brother 20[12] and is a Facebook Watch exclusive.
