The pair had a go in the short-lived US version, but quit after just a few days.
But seemingly their three week stint in the Big Brother house has prepared them for another British reality show.
As well as I'm A Celeb, the pair are apparently preparing to star in their own reality show which will see them tour the UK.
Speaking to the Daily Star, Heidi also revealed she hoped to move to the UK permanently and start a family of little Pratts.
She said: "I would totally live here. We didn’t like the boring British people we were in the house with but since we’ve been out we’ve really fallen in love with the country.
“I want to be posh like Princess Kate or Victoria Beckham.”
Heidi went on: “For me, having children is the greatest experience in life – but Spencer doesn’t want them.
“My priority is my husband and so now I choose our life instead of that experience.
“But the beauty of life is that we may change our mind. It’s only going to happen if we are both in that situation and in the same mind.”
If they pair do enter I'm A Celebrity they could end up coming face to face with CBB winner Rylan Clark, who is also tipped to take part.
