Kim was a big star in the 80s in the US and the UK with hit songs including 'Kids in America'
She stepped out in once vertically sprayed bleach-blonde hair piled loosely atop her head in a shaggy ponytail, and her face unblemished by the heavy eyeliner she once favoured.
And she was practically unrecognisable from her chart-topping days as she enjoyed a spot of shopping at boutique Agnes B.
Her make-up free face exposed her weather-worn looks, and clearly her work outdoors as a gardener has taken its toll on her once fresh-faced look.
Dressed in tight black jeans, and a faded t-shirt, the former singer looked a world away from the confident young rocker who stormed the UK and US charts with her debut single.
The daughter of Fifties and Sixties pop star Marty Wilde, Kim performed in concert all over the world. She released ten hit albums and more than 30 singles.
She is due to make a brief return to music, as a DJ on Virgin Radio as a DJ over the Easter weekend.
Kim will present Virgin Radio Party Classics between 6pm and 10pm, replacing regular host Tony Hadley, the former Spandau Ballet singer.
"Kim is an absolute 80s icon and a sex kitten to boot," said Mark Bingham, the programme manager at Virgin Radio.
