The 42-year-old star - who is dating Spanish model Andres Velencoso - would love to start a family but is unsure whether she is able to still conceive following her battle with breast cancer in 2005.
Kylie - who is still taking several drugs to ensure the disease doesn't return, and will do for at least another year - said: "I do feel incredibly broody. But I have to be honest and accept that with everything I've been through I don't know whether I will actually be able to have children.
"I would absolutely love to but I don't think it's going to happen."
In the meantime, the 'All the Lovers' singer consoles herself by spending time with her brother Brendan's son Charles and is awaiting her sister Dannii giving birth to her first child.
She told Grazia magazine: "I'm so excited for Dannii, I can't wait for her to be a mum. I have a little nephew already who I am totally obsessed with. Spending time with him is one of the most incredible things I ever do. When I'm with him I turn into this woman who rolls around on the floor playing for hours, I change his nappy and I love it."
