The former glamour model has had several boob jobs and dozens of other cosmetic procedures over the years and believes space travel would do wonders for her appearance.
Speaking ahead of the Blu-Ray 3D release of blockbuster movie Gravity, Katie said: "I tell you something, I would look amazing in space with my chest.
"Gravity would go the other way wouldn't it? I'd look all young and pert again."
Katie - who married third husband Kieran Hayler last year and who is mum to Harvey, Junior, Princess and Jett - also revealed what she would take into space if she ever had the opportunity.
"I'd obviously want to take the family, Kieran and the kids because they would love it," she said.
"[And] moisturiser, because I hate having dry skin and stuff."
Last night, it was all fun and games in the Price-Hayler household. To mark Pancake Day, Katie took pictures as Kieran tossed up a treat in the kitchen.
