Davina McCall says she would sacrifice her career to have more children.
She is set to host a new series of Big Brother from May 24, as well as her new ITV1 quiz show The Vault.
She says she wants to extend her family as soon as possible and would give it all up tomorrow.
Davina and husband Matthew Robertson have just moved into a new six-bedroom home in Surrey, with eight-month old daughter Holly.
She tells the Daily Mirror's Look magazine: "I want to extend our family as soon as possible. I hope to have loads more kids. Being a mum is the best thing that's happened to me. It is more important that anything. It puts work into perspective.
"I wanted to live in a big house in the country with ponies and pot-bellied pigs, and children tugging at my dress.
"It's cost us squillions and it's a whopper. It's got an acre of land, enough room for the dogs and babies and swings and donkeys. Call me Mrs Robertson, I love it."
