The TV star joined Countdown in 2008

Rachel is known for being the maths whizz on Channel 4's iconic game show. She initially considered a career in marketing, before her mother encouraged her to audition for the daytime series.

When Countdown's original 'human calculator' Carol Vorderman retired from her role in 2008 after 26 years, Channel 4 began searching for an unknown host to replace her. Rachel, then 22, beat 1,000 other applicants to win the coveted role as resident maths guru.

She also met future husband Pasha during the 2013 series of Strictly Come Dancing. They secretly tied the knot in Las Vegas in June 2019, and then became first-time parents in December of that year. This autumn, the couple are set to welcome their second child.

In a recent interview with MailOnline, the TV star confessed that both she and Pasha were unsure about having children in the early stages of their relationship. Having had time to reflect, the pair decided to go ahead before it was too late. "We've bashed them out! Get the sleep deprivation over in one go is the plan," she said.

"I'm 35 and I've got friends that are struggling with fertility, and you just never know if you're going to be able to get pregnant, we have been really lucky, touch wood and we're very excited. They're great, we weren't sure if we wanted them before and we're just both in love, it's lovely."
