Her divorce from Graham Quinn was finalised in just 100 seconds earlier this week.

And for her first public appearance as an officially single woman, Myleene Klass channelled her Hear'Say days and kept it Pure And Simple in a figure-hugging white dress.

The mother-of-two highlighted her incredibly slender frame in the fitted dress, which boasted a sweetheart neckline to draw attention to her cleavage, as she arrived for her Mothercare photocall.

Adding some interest to the ensemble, Myleene teamed the dress with a slick of bright red lipstick and leopard-print heels.

The 35-year-old star was launching her tenth collection for the high-street store, and looked confident and sophisticated as she headed into the Oxford Street store on Thursday.

Anticipating her arrival, Mothercare tweeted: ‘Love #BabyK? @klassmyleene will be launching her 10th season range at Mothercare Oxford Street today morning.'

Myleene - mother of two girls Hero and Ava - posed with her Baby K models, Kayla Mae, Jayden Bell, Zachary Sharp and Ruby Brown mark the launch of the new collection at the Mothercare Oxford Street store, London.

The designer said she's 'thrilled' to be bring out another range with the high street retailer.

'I'm thrilled to be celebrating the 10th collection of Baby K with Mothercare.'

'Children's fashion is a passion of mine and it's been amazing to work in collaboration - exclusively with Mothercare over the last five years to create a range of clothes designed especially for children that can be stylish yet still practical and affordable.'

'We hope the new range, inspired by fashion from around the world, will bring a little bit of fun and colour to children's wardrobes this summer!' Myleene shared on Thursday.

Mothercare are equally excited, with CEO Simon Calvers saying: 'We are delighted that Baby K has been so successful with our customers since its launch in 2007.'

'The Spring/Summer 2013 collection marks 5 years of offering our customers exactly what they want from Mothercare - exceptional quality and style at an affordable price'.

But the baby and toddler retailer have been suffering from bad sales this year, thanks to supermarkets enticing their customers away with similar products at a lower price.

However, Calver, says that celebrity ranges from the likes of Myleene and Jools Oliver (wife of Jamie) are still bringing in revenue even though the company are still closing down stores to save money.

Their new value range - brought in to compete with their supermarket competitors - is helping them hold on.

‘Value is now 20% of our sales,’ Calver told the Daily Mirror.

The new Baby K collection has two French themes: Paris and St Tropez.

The former is filled with Breton stripes and quirky bows for girls and lightning bolt prints and surrealist graphics for boys, while the latter showcases tropical floral, leopard prints and wildly bright prints.
