The 33-year-old TV star has been married twice - first to Peter Andre, who she has two children, Junior, six, and Princess Tiaamii, four, with and secondly to Alex Reid, who she divorced after a year of marriage in February 2011 - believes there are more spouses in her future, as well as more children and a second shoot for Playboy magazine.
Katie - who first appeared naked in the pages of Hugh Hefner`s magazine in 2002 - said: "I`ve got another Playboy shoot in me. I still love getting my kit off because it`s what I do best and it`s got me where I am today. And I`ve also got plans for a film and a West End show.
"I`ll also have more kids, more horses and probably more husbands, about 12, I expect!"
However, Katie - who also has nine-year-old son Harvey from a previous relationship - admits she still has "issues" with her ex-husbands, despite being in a new relationship with Argentinean model Leandro Penna.
She said: "I think all of these experiences were meant for a reason because they remind me not to take anything for granted.
"I still have issues with both my exes but I just have to deal with it. Everyone has a drama, don`t they?"
