Singer Nicole Scherzinger is preparing to be a hands-on mum in her 40s.

The former Pussycat Dolls star, who has been dating British Formula One driver Lewis Hamilton on and off since 2008, wants to focus on her career and has put the role of mother firmly on the back burner.

The 34-year-old star wants to wait five years before beginning a family, insisting she has no concerns about being an older mum, citing egg freezing as a viable option.

She tells Britain's Marie Claire magazine, "I'm not getting any younger. I don't want to have kids now though. I'm not going to be one of those mums who has nannies. Actually, I might have nannies - never say never- but I'm not having someone else raise my kids.

"I think five years might be a good time to look at having children, but I think whenever it's meant to happen is when it will happen. Right now, I'm focusing on my career.

"I see lots of women having beautiful children later in life now. And, if not, just freeze your eggs!"
