The line-up and broadcast date has been confirmed for the first episode of the new celebrity panel game show fronted by comedians Lucy Beaumont and Jon Richardson.

Richardson and Beaumont put their own marriage flaws to one side in order to judge everyone else's, by inviting two unsuspecting celebrity couples to go head-to-head to decide who has the best relationship. The first of six episodes features Countdown maths whizz Rachel Riley and professional dancer Pasha Kovalev, and comedians Richard Herring and Catie Wilkins.

The celebrity couples take on some patience-testing challenges, including a nightmare makeover, tackling an impossibly dirty bathroom, and a rather alarming lie detector test in which one of the stars is outed as a shower pee-er...

Other guests in the series include Jack Whitehall's parents Michael and Hilary, Ore Oduba, Harriet Kemsley and Bobby Mair, Sara Pascoe and Steen Raskopoulos and Vicky Pattison.

Jon and Lucy's Odd Couples, Fridays from January 13, Channel 4, 9pm.
