Comedian Chris Ramsey is one of the stars taking part in this year's Celebrity Crystal Maze.

Richard Ayoade returns to guide more celebrity adventurers on an epic quest through the four fantastical zones of The Crystal Maze - Aztec, Industrial, Futuristic and Eastern - in a brand new series.

Within the zones, the teams face a host of Skill, Physical, Mystery and Mental challenges in a bid to win precious crystals, which they will exchange for time in the legendary Crystal Dome.

This time, TV presenter Laura Whitmore captains her team - comedian Chris Ramsey, dancers Perri Kiely and Jordan Banjo, and former rugby player Gareth Thomas - through the maze. The celebrities risk everything, even breaking several course records along the way. But will their efforts pay off in the Dome, where the tokens never lie? 

Ramsey, who is from South Shields, is married to Rosie Winter. They married in 2014. They have one child with another one on the way, due in January. The couple have a hugely successful podcast, Shagged Married Annoyed, which they are taking on tour in 2021.

Richard Ayoade is married to Lydia Fox, who is a member of the Fox acting family. Her father is James Fox and her brother is the controversial Laurence Fox. Emilia Fox and Freddie Fox are her cousins. They live in South London with their children.

The whole series will be available to stream or download for free on All 4 following the transmission of the first episode, on Thursday 3 December, 10pm, C4.
