Carol Vorderman is the latest addition to Celebrity Gogglebox.
The maths whizz is best known for appearing on Countdown for 26 years between 1982 and 2008 before the role was taken over by Rachel Riley. As well as being the face of the hit Channel 4 show, Carol has hosted the Daily Mirror's Pride of Britain Awards since 1999.
The former Countdown host has been joining long-term friend, This Morning's Gyles Brandreth on his sofa as they enjoyed the week's latest TV programmes together. Speaking of having Carol join the cast, Gyles said: "We are very old friends but I had forgotten how easy it is being together, just fun and having the programme to chat about with snacks."
