Ana Matronic finds the thought of having children "terrifying".
The Scissor Sisters singer - who married artist Seth Kirby in 2010 - likes the "idea" of starting a family but worries she's too busy with her career and wouldn't want to be an absent parent.
Asked if she wants children, she said: "I like the idea of it, but the reality is terrifying because I just have so much to do - I would want to be the kind of parent who has enough time."
The 41-year-old star and her husband have been working to renovate their home and are excited that the work is almost done.
She added: "I love New York and I love my home, I live in Brooklyn. We are still renovating but we are actually almost done.
"We have lots of space. We also have a two bedroom flat to rent out to friends sometimes."
Ana's parents split up when she was a child because her father was gay and she admits she didn't really understand his sexuality when she was growing up.
She said: "When I found out he was gay I was six. It just meant to me that mom and dad never got back together.
"I didn't really know what it meant to be gay. It was never a problem to me, he was still my dad."
