The 37-year-old supermodel - who has an eight-year-old daughter, Lila, with former boyfriend Jefferson Hack - is focused on her forthcoming wedding to Jamie Hince, and says she and the 40-year-old rocker will consider starting a family together once they have tied the knot in July.
She said: "First of all I am going to get married. And maybe more kids? Who knows what the future will bring. My career is okay so far, anyway."
The British beauty admitted she felt she had "made it" when she gave birth to her daughter in September 2002.
She told German magazine Gala: "When I gave birth to Lila, after I did it I was just thinking, 'Yeah! I really made it!' "
Kate also revealed she is attracted to older men, including Rolling Stones frontman Sir Mick Jagger, 67, and 64-year-old David Bowie.
Asked who she finds attractive, she said: "Mick Jagger, David Bowie - all those sex gods of rock."
Kate often features on Best Dressed lists, but could be set for a change of image after being inspired by eccentric pop star Lady Gaga.
She said: "Lady Gaga gives you the feeling it's OK to be able again to get really dressed up."
