The singer, who has been dating Spanish model Andres Velencoso for three years, hates people asking her about having babies.
The 43-year-old loves her three nephews but doesn't know if a family is on the cards for her just yet.
Minogue's sister Dannii welcomed her first child, Ethan, last year - and her brother, Brendan, has two sons, Charlie, five, and two-year-old James.
She told British YOU magazine: 'I hate the question, 'So, are you going to have children?' But amazingly I have never had it from my mum or dad. They never put pressure on any of us.
'For a while it looked as if it would never happen for us all and then boom, boom, boom. The only answer I have is, if it happens for me - beautiful. I'll have to wait and see. I love children and I love the thought of having a family. And Andres is really good with kids.'
While the pop star hasn't ruled out having children in the future, she is happy at the moment just doting on her nephews.
Minogue added: 'My brother Brendan's son Charlie is five now and his little brother James is two, and Dannii's boy Ethan is one. They all came to see the show when we were in Melbourne and I could see them from the stage. I kept looking over to see if they were still there - halfway through, James couldn't cope and was asleep in my dressing room. Ethan was swaying on his father Kris's shoulders - he stayed for maybe five numbers - and it was wonderful.'
