Francis Brennan has revealed he was asked to join Dancing With The Stars - but said no for health reasons.
The TV personality said he was approached to appear in the first series, which began airing in January last year.
However, he decided he was better off sitting it out because of a busy work schedule and a problem with his foot.
"They asked me already," he said. "I was asked the first year. I would love to do it, but first of all, I don't have the time, never.
"I spend four to six weeks working in America between February and March. I've done that every year for the last 40 years.
"Also, I have a bad foot which I don't think I need to aggravate. The doctor told me I could be crippled from it when I was 40."
"I'm 64 now, and I'm going grand, so I don't think I would do it from a medical point of view.
"Also, I don't have the time. I told them that from day one."
The new series of Francis Brennan's Grand Tour kicked off last night on RTE One with a new crop of travellers accompanying the hotelier on a trip to South Africa.
"It was a great trip. Nothing went wrong, thanks be to God. We had people from their 20s to 83 years of age.
"We had a great mix of people and they were game for everything. They walked with lions and did bungee jumping. It was fantastic."
When asked if he was ever worried about any of his fellow travellers being injured on their trips around the world, Francis said extensive background checks were done to ensure they are fit enough to take part in the show.
"We do a lot of research off camera to make sure everything is all right," he said. "If someone had a bad heart or something we would probably say no and pick somebody else because it's just a safer bet.
"But we've been very lucky. Last year we had an 80-year-old and this year we have an 83-year-old so we're going up, rather than down."
Francis Brennan's Grand Tour South Africa airs on RTE One on Sundays at 8.30pm.
