The singer married her bodyguard Wayne Newton in 2007, but she is adamant the couple won't be having children.

She says, "He has two beautiful boys. Neither Wayne nor I want more children.

"I am really honoured to be a stepmum and he is such a good dad. At 40 and with a career, it just seems like a really tall order that I'd be changing a diaper."
