Michael Buerk is to use his experience on I'm A Celebrity ... Get Me Out Of Here! to tackle the issue of reality TV on the Radio 4 show he presents.
He will step back behind the microphone for the first time since returning from the jungle for tonight's edition of The Moral Maze, appearing as host and also as a witness to share his views.
Veteran newsman Buerk, 68, was a surprise inclusion on ITV's I'm A Celeb and during his time in Australia viewers saw him show off a new-found skill as a rapper.
He is heading straight back to his day job hours after returning from Down Under, following the finale of the TV contest on Sunday night which was won by Carl Fogarty.
Speaking on Radio 4's Today programme, Buerk said: "I will be sharing my own insights."
Giving his initial thoughts on celebrity reality TV, he said: "Oh, I think it's hateful - no, not hateful, but questionable."
Asked whether he had any regrets about taking part, he said: "Regret is too simple a word really. I'm waiting until the dust settles."
In The Moral Maze, expert witnesses are called to discuss the ethical issues of the day.
In a trail for tonight's programme, he said: "As some of us have more reason to know than others, this is high season for reality TV.
"Is this cultural corrosion a load of attention-seeking non-entities being humiliated for the amusement of the vacuous, or 21st century morality plays that stress-test the people and preconceptions the modern world holds dear?
"What's celebrated about celebrity, which for the first time in human history, perhaps, appears to be divorced from achievements or virtue?"
The programme airs at 8pm tonight.
