- a former actress and model who opted to trade in showbiz and stilettos for mucking out on the farm - had a heart-to-heart with Prue Leith about what life is really like on . Speaking on her Cotswold Kitchen show, 85-year-old Prue gently quizzed whether she was "mad".

"[You've] now swapped a life on the catwalk, in the social whirl, for a life farming in the Cotswolds, in the mud, all hours of the day and night with boyfriend . I think you must be mad!" she bluntly exclaimed. Lisa shot back that she loves "mud and guts" as she's a "true land girl" - but there have been moments that have had her in uncontrollable tears, which she candidly shared with Prue. Despite the inevitable fate of pigs on the farm, and Jeremy's documented love of bacon, both were heartbroken when a sow became so sickly that she could no longer raise her babies.

Too weak to walk or eat, the exhausted pig had to be put down to prevent further suffering to her - and that was the moment when usually the poker-faced Lisa let her guard down and cried.

She confided to Prue: "I'm not a crier. Jeremy... I don't think he'd seen me cry [before that day.]

"'My shoulders started going and I was like: 'Oh no, not now. I'm going to cry.'"

There was another traumatising moment when Lisa had to become a makeshift midwife to help a sow give birth - and there were casualties.

The hands-on experience made Lisa feel compassionate and close to the mum and babies, and it was a tear-jerker too.

Prue praised: "One of the best moments I have seen on television is Lisa Hogan playing midwife.

"It was so emotional because half of [the piglets] were dead, you were crying but you were not stopping doing the job!"

However, there were success stories too, with one of the surviving piglets growing up strong enough to birth a litter of 14 - and that time, all of them thrived.

Lisa's role on the farm is constantly growing, with the ex-model writing her own book, launching her own brand of apple juice and becoming a key Clarkson's Farm character in her own right.
