Kim Kardashian "absolutely" wants to have children - but not for a few years.

The 31-year-old socialite - who has been romantically linked with former boyfriend Reggie Bush since splitting from husband Kris Humphries in October after just 72 days of marriage - still wants to have a family but not just yet as she wants to keep her curvaceous figure the way it is.

"Do I want kids of my own? Absolutely. But I don't know if that's what's meant for me. Maybe I'll just work, work, work, and not think about it. [My sister] Khloe joked with me and said, 'Will you be my surrogate?'"

But for the moment Kim wants to keep her shape instead of having a baby: "I said, 'I think I have a couple more years when I just want my body to myself. At 35, I promise I'll consider it.'"

Kim also admitted her public nuptials and the subsequent fall-out from the demise of her marriage - which has been the subject of speculation it was a fake union designed to boost ratings for her reality TV shows - has taught her to be more private about her personal life in future. "[The experience has] definitely made me want to be more private with my relationship, whenever I choose to get into one again. I'm not ready, but when that time comes, I'll be more cautious about who I let my world open up to," she told Allure.
