Sugababes star Jade Ewen does the highland fling as she models tartan lingerie for new Miss Ultimo collection

She's been the face, and body, of Miss Ultimo for the past year, but this is surely Jade Ewen's sexiest shoot to date.

The 23-year-old Sugababes star sizzles as she models a variety of pretty and flirty lingerie which form part of the Miss Ultimo Valentine's collection.

As well as sticking to traditional red underwear, Jade also pays tribute to her part-Scottish roots in the Highland Fling two-piece set, featuring tartan detailing and a cute frill on the bottom.

Talking about the new collection, Jade, who is dating EastEnders star Ricky Norwood, said: 'I love the new Miss Ultimo Valentine’s collection. It’s really pretty and lots of fun, perfect for celebrating the most romantic day of the year.

‘There’s nothing quite like sexy underwear to say “I love you” and to woo your lady. My boyfriend has never been brave enough to buy me lingerie, but I’m keeping my fingers crossed for this year.’

Miss Ultimo creator Michelle Mone, OBE, added: 'Any men wondering what to get their lady this Valentine’s, here’s your answer.

All smiles: Jade looks adorable in the new range

Jade has an incredible figure thanks to her dancing background and constantly busy schedule with the Sugababes, but admits she was dubious at first about doing an underwear campaign.

She said: 'I didn’t actually think I’d ever do a lingerie campaign but I have always been a huge fan of the Miss Ultimo brand and Michelle that I simply couldn’t say no. I was really delighted to be asked to do it.'

And, since having worked with Miss Ultimo, Jade has actually put some of the knowledge she has acquired in the role to the test.

She said: 'First of all, make sure you’re wearing the rights size.

'It wasn’t until after I was appointed as ambassador of Miss Ultimo did I think I’d better get measured, and sure enough I had been wearing the wrong size.

'Wearing the right size really improves your silhouette and gives you the right support.'

Talking about her collaboration with Miss Ultimo, Jade said previously: 'I’m a total fashion addict, so being involved with a lingerie brand that’s so fashion-driven is lots of fun.'

And creator Mone added: 'Jade has a beautiful, healthy figure and a natural flair for fashion, which works incredibly well with the Miss Ultimo brand.

'She’s exactly what Miss Ultimo is all about in terms of her style, spirit and energy.

'We’re really excited to have her on board.'
