Rachel Riley, 33, recently celebrated 10 years of being on the Channel 4 show, after she replaced Carol Vorderman, 58, who quit in 2008. The blonde beauty was joined by her co-stars Nick Hewer, Susie Dent and special guest, comedian Rufus Hound who sat in the Dictionary Corner, on today’s show. Rufus took the opportunity to deliver a poem about the show’s cast, where he cheekily joked Rachel was not a natural blonde. He said: “Rachel’s transformation’s crazy. A natural blonde you’d be mistaken.
“If anything she looks younger now than when this snap was taken.”
As his poem came to a close, Rufus turned the framed photo he held in hands toward the camera.
The snap featured the original line-up of Countdown – including Carol, who sported dark brunette hair and original host, Richard Whiteley.
Rachel seemingly appeared to see the humorous side, as host Nick applauded the comedian, saying: “Priceless.”
Carol was also a mathematician on Countdown, where she starred on the show for almost three decades before her departure in 2008.
She appeared on the show alongside Richard, who died in 2005.
Meanwhile, Rachel and her Strictly Come Dancing boyfriend Pasha Kovalev, 39, got involved in a funny exchange as they both realised they were clueless about the meaning of the term “third base” on Celebrity Gogglebox.
The couple addressed the sexual comment while watching bawdy comedy American Pie during last week’s episode of the show.
The pair who are expecting their first baby together, appeared to be baffled by the suggestive comments made in the movie by character Jim Levenstein.
Describing an intimate stage in a relationship, the teenager, played by Jason Biggs, 41, said to one of his pals: “Correct me if I’m wrong but you’re the one with the girlfriend and you’re still on third base.”
The cheeky conversation in the film prompted confusion from Rachel and Pasha, who were relaxing on their sofas in front of the TV.
The Russian dancer instantly turned to ask his beau in response: “Hold on, what’s third base?”
Unfortunately, Rachel was just as bemused by the subject, as she admitted: “I’ve never understood bases.”
She then asked: “Is second [base] touching boobs?”
The couple also spilled on the gender of their baby in a previous episode, with the TV personality said to her other half: “It’s too early.”
In reference to a recent sonogram, she added: “I can’t see a penis!”
Countdown airs weekdays on Channel 4 at 2.10pm.
