Dame Prue Leith is to front an assisted dying documentary alongside her son.
The 'Great British Bake Off' presenter - who is a member of the campaign group Dignity In Dying - will team up with her son, Conservative MP Danny Kruger, for the new Channel 4 programme.
A TV insider said: "Viewers will see a very different side to Prue in the programme as she strongly supports assisted dying."
Prue, 82, and Danny, 48, will head to the US and Canada to find out more about assisted dying.
The insider added to The Sun newspaper's TV Biz column: "In contrast, her son Danny is opposed to the idea, claiming it’s risky because it opens the doors to abuse and exploitation.
"So the resulting conversations they’re likely to have on their journeys will make for interesting viewing."
While Prue doesn't agree with her son's stance on assisted dying, she is said to respect his views.
The pair's Channel 4 film is expected to air next year.
It comes after Prue admitted in her recent memoir, 'I’ll Try Anything Once', that she drowned a bag of kittens as a child.
She said: "My mother and I, then 11, had just drowned some kittens … and for weeks I imagined those poor dead creatures.
"Too many kittens was a frequent occurrence and there had come a day when my mother, unable to find homes for yet another litter, decided to drown the latest batch.
"My protests were met with a firm, 'Darling, it has to be done. They are only a few hours old. They will hardly know it’s happening'."
Prue's mum explained to her that she didn’t need to hold the bag for too long to send them to "sleep".
However, the TV star can still remember the kittens fighting "like the devil" for life.
She added: "I held the bag under water until the last kitten had stopped mewing."
