CAROL Vorderman, 61, is unrecognisable in a new snap shared on her social media from her Countdown days.
The star is perhaps best known for co-hosting the game show for a whopping 26 years, from 1982 to 2008.
Carol has been on the show more times than anyone else, with a huge 4,832 appearances as an arithmetician.
Countdown was Channel 4’s highest rated show throughout the 80s and 90s with 4-5million viewers every day.
And in a nod to Channel 4, Carol shared her throwback in which she can be seen back in her days on the show sporting darker locks and a fringe.
