The Kill Bill star began dating a 26-year-old man known only as Slimm at the start of 2010 and they briefly split in August (10) before reuniting again.
Now the 46 year old reveals the couple is planning on trying for a baby as soon as her stint in touring play Cheaper to Keep Her wraps early next year (11).
Asked whether Slimm is "The One" for marriage and babies, Fox says, "Yes, absolutely. My career has been my baby for such a long time and I waited for God to send me a good man.
"I got to finish this tour first, but after this tour we're planning to do the thing (try for a baby)!"
Fox admits she would be open to adopting children if she fails to conceive naturally, but insists: "I'm very fertile, so I don't think I'll have a problem."
