Carol Vorderman was left in giggles on Friday's This Morning when her co-panellist and friend Gyles Brandreth made a cheeky remark about her love life.
The Countdown star has spoken previously about her "special friends" when asked about her relationship status.
During a discussion on the sport bowls trying to recruit younger members, Carol said: "My friend Nathan in Cardiff at the end of his road, and he's in his forties..."
Interrupting, Dermot O'Leary quipped: "Is he one of the magic five, Carol?"
"No, he isn't," Carol replied before Gyles later explained: "People who have just tuned in may not know about the magic five. My friend Carol has quite a complicated love life."
"It's not complicated," Carol hit back as Alison Hammond jump into defend her: "They're just special friends!"
Gyles continued: "When I was a young boy I read the Famous Five by Enid Blyton and I know feel I have matured because at night I go to bed, hearing stories on the phone from my friend Carol about the magic five."
Carol opened up on her love life earlier this year during an interview with Michelle Visage on her Rule Breakers podcast.
The Countdown star admitted she was single but had several "special friends".
When asked if she was in a relationship, Carol replied: "No! I'm having the best time. I've spoken about this once. I have a system which I've had for ten years. They're called 'special friends'.
"I spoke a couple of months ago about having 'special friends' and it was like, again, the world had fallen in for some people but actually what I found was there was an awful lot of women who said, 'I'd never thought about it like this.'"
Carol revealed that she's dated one of her "special friends" for 11 years and one for seven years before revealing she's "not into one-night stands".
"The language around a woman of my generation is that if you had more than one partner when you got married you were this you were that," she added,
"Everything was derogatory about a woman, that was the environment I was growing up in. It was like 'she's desperate', everything was judgmental."
