Davina McCall has "an agreement" with her boyfriend not to talk about their relationship in public.
The 'Masked Singer' judge and her partner Michael Douglas, 47, don't discuss their romance because their exes and kids "don't have a right to reply".
She said: "We’ve got an agreement that I don’t talk about our relationship, because our exes and kids don’t have a right to reply, so it’s not fair.
"But I love doing the podcast with him. It’s basically an extension of what we’ve always done as friends, which is recommend things to each other.
"Even if we didn’t make any money - which we haven’t really, yet - we would still do it just because we love it.
"People also seem to really love it. But I guess that is the most public thing we do together."
Davina - who has children Holly, 20, Tilly, 18, and Chester, 15, with her ex Matthew Robertson - admits she and Michael seem to have more time in the evenings nowadays because their kids are older and off doing their own things.
She said: "Now our kids don’t want to talk to us any more because they’re older, we’ve got all this lovely extra time in the evenings to learn what we want to do next.
"It’s a great time when you can move from the bottom of the list to the top and begin exercising again. Just make a start. It’s never too late to start exercising. Never."
But the 54-year-old star insists she tries not to speak to her kids about their bodies, and only ever tells them to cover up if she fears they will get cold outside the house.
Speaking to OK! magazine, she added: "Even when I say to them, 'Are you going to go out like that?'
"I’m talking in terms of getting cold rather than, 'You’ve got to cover up your body.' We never talk about weight or weigh ourselves, it’s just not a thing. And in fact, because it’s not a thing, it has never been a thing."
