Dannii Minogue is thankful she's not having twins

The 38-year-old singer – who is pregnant with her first child to her former England rugby playing boyfriend Kris Smith – hasn't found out the sex of the baby but is relieved that medical checks have ruled out a multiple birth.

She said: "I don't know if we'll find out what we're having, we haven't had a chance to think. We know it's not twins – the doctor said this morning that there's only one in there and Kris and I both sighed with relief! I'm so tiny, I'm not big enough to fit twins in there – I wouldn't be able to stand up!"

Despite being happy with her pregnancy, Dannii admits she took "some convincing" about starting a family with Kris because her own parents did such a good job raising their children.

She told Britain's Glamour magazine: "I have two loving parents who formed a family around me and I have it in my mind that I want it to be like that. I would only do it if I was able to recreate that and up until now, I've never been in a relationship where I was 100 per cent confident and had those feelings.

"Kris was ready from the word go and couldn't wait to start a family. I've taken some convincing, but we've taken the leap together and it feels right. Kris is The One."

Although Dannii - who was previously married to actor Julian McMahon – is content in her relationship, she is terrified of walking down the aisle again because her divorce affected her so badly.

She said: "Marriage really scares me. I wouldn't rule it out, but my divorce was really emotional for me. My weight plummeted – I was skeletal and it wasn't pretty or healthy but I couldn't control it. When something is wrapped up in all these bad memories, you don't want to go hurtling back there."
