Dannii Minogue feared she was too old to get pregnant.

The 38-year-old Australian singer - who announced earlier this month she is expecting her first child - was stunned when doctors warned she would struggle to conceive, but tried to pretend she didn't care her biological clock was ticking down.

She told the Daily Mirror newspaper: "A while ago I went to my doctor for a check-up and he told me I'd got to the stage in my life where I'd have to make decisions about having children.

"I remember thinking, 'Oh God. I'm now that person who is getting too old to have kids.'

"I told him it wasn't an issue for me because I didn't have a man, there was no one on the horizon, and there probably never would be."

Things turned around for Dannii in 2008 when she met British ex-rugby player Kris Smith, 31, while holidaying in Ibiza.

The star - who currently splits her time between Australia and the UK - says Kris is a calming influence on her anxious nature, but admits they are currently having problems deciding where to raise their child, with the model applying for citizenship in her home country.

She added: "Kris is so completely broody. I'm totally in a panic about everything - babies, living together and working miles apart. It all seems so complicated.

"I am exploding with happiness. But, hey, it's wonderful to have problems caused by being completely in love.

"My life has been turned upside down, inside out and everything. I mean everything is fresh and new and exciting."
