Natasha Hamilton is currently pregnant with her fourth child, her first with boyfriend Ritchie Neville.

And, despite admitting that she's been suffering from "the worst morning sickness ever", the Atomic Kitten star looked positively blooming as she custom-designed a pram for her little one at an event in London.

Natasha, 31, opted for a gorgeous floral mini dress, which had cut-out details on the shoulders, with a pair of strappy red heels.

Throw on some red nail polish and a slick of beautiful nude lip gloss, not to mention those tumbling red waves, and Natasha looked primed and ready for summer.

Tweeting from the event at Peppermint's boutique in Chiswick, she happily announced to her followers: "Just custom designed my beautiful new @JoolzUK buggie @peppermintuk in chiswick #verycosybaby x"

The Joolz Day Tailor, which retails for £999, is the first customisable pushchair on the market, and offers customers the opportunity to choose from 120 different colour combinations.

We can't help but wonder what colour Natasha went for - could it have been a pink or a blue buggy?

Well, judging by recent comments on the Lorraine show, Natasha, a mother of three boys, is pretty confident that this time she's expecting a little girl.

"The boys would like a sister. I think there might be enough testosterone in the house already."

And she added that she feels different about her pregnancy this time, saying she'd been feeling "really hormonal" and "really, really sick".

Meanwhile Ritchie, who reckons he had predicted Natasha's pregnancy when he realised she smelled of newborn babies, said of the happy news: "It definitely is a life changer, even just on perspectives on the world and stuff, the world's a different place all of a sudden."
