Kylie Minogue is worried she'll have to start using "walkie-talkies" to communicate to her boyfriend when she's older.

The 5ft 1in singer fears she'll start to shrink in the future and admits if she does it will make talking to her 6ft 4in boyfriend Andreas Velencoso very difficult.

The 43-year-old beauty said: "I'm still waiting for my growth spurt. It's never too late. I'm sure I'm going to end up about 4ft 10in. My boyfriend is around 6ft 4in so we'll end up communicating with walkie-talkies in the future. But I guess that's why God invented high heels."

Kylie - who successfully beat breast cancer in 2005 - also revealed how she gets fed up with people always asking her whether she's going to have children.

She told Stylist magazine: "It's such a personal question and between my age and being a cancer survivor, it's a different story to when I was asked this 25 years ago. I get it; I get that people want to know and all of that but it does start to get boring Slash annoying. I have started to refuse to answer certain questions but it took me a while to understand that this was fully acceptable. I think that confidence only comes with time."
