Countdown bosses are said to be 'desperate' for Carol Vorderman to return following the news that Anne Robinson has quit the show.
Anne, 77, confirmed earlier this week that she would no longer be fronting the Channel 4 series because she wants to spend more time with her grandchildren.
The TV star, who recorded 265 episodes of the show, said of her decision to quit: "I've had a blast hosting this wonderful show. And I stayed longer than I signed up for. Now it is time for an older woman to take the reins.
"I hope too I've encouraged TV bosses to realise that not all women at the wrong end of their seventies are in care homes playing bingo and watching conjuring tricks," she continued.
Fans of the show quickly began to speculate on who could replace Anne, and former Countdown star Carol seemed like a strong contender.
Amid speculation that she would return and help boost ratings, mother-of-two Carol broke her silence and tweeted: "Thank you to all of you saying such lovely things about a possibility of me returning to Countdown.
"You're very kind & it would be an honour but I want to wish whoever is the lucky human to be the new host all the love and 9 letter words in the world #CountWell#HappyDays."
However, it's highly unlikely that Channel 4 bosses will give up that easily as a A TV insider told The Sun: "Carol is such a big part of Countdown and Channel 4 know how much everyone loves her.
"Bosses would love her to come back as the main host, her Countdown journey would come full circle. It would be perfect."
Carol appeared on Countdown from 1982 until 2008 after her own mother noticed a newspaper advertisement asking for "a woman with good mathematical skills" to appear as co-host on a quiz show and submitted an application on behalf of Carol, who was just 21-years-old at the time.
Carol recorded her last Countdown show on November 13, 2008, which was broadcast on December 12, 2008.
