Pretty in purple: Pixie Lott poses in a sexy cut-out dress from her new range for high-street store Lipsy
She might be most well-known for her vocal talent and musical styling, but Pixie Lott is also causing waves in the fashion industry.
After three hugely successful collaborations with high-street store Lipsy, Pixie is teaming up with the company once again for a fourth range of clothes.
In this exclusive shot obtained by MailOnline, Pixie is seen donning a sexy purple cut-out dress as she shoots the campaign for the new range.
While details of the new collection have yet to be released, various dresses can be seen hanging in the background - including a black and pink strapless minidress and a black and gold floaty number.
The outfits certainly show Pixie has evolved since her first ranges with Lipsy, when she concentrated on festival chic outfits with playsuits and shorts among the most popular items.
In the last collection, Pixie tried to mesh two different styles of clothing - Pixie Party, featuring more evening-style outfits, and California Dreaming, the festival-led more daytime collection.
New look: It seems the new range represents a new grown-up side of Pixie
Talking about the range, Mama Do singer Pixie said at the time: 'I'm having such great fun turning my fashion ideas into another exciting range and am overwhelmed with the response so far.
'This time I've taken my inspiration from the floaty feminine florals of the '70s to the neon brights of the Miami party scene and what I love to wear out with my friends.'
Pixie's new range for Lipsy, which will launch in stores and online at Lipsy.co.uk at the end of September, comes as it's announced the singer has been signed up by model agency Select.

Talking about her new venture, Pixie said: 'I've always loved experimenting with different looks and styles through work - it's one of the perks of the job!
'I've always been surrounded by clothes, and I love fashion and accessorising.
'I've learned a lot about what works and what doesn't, which has helped to build my confidence and interest in fashion.

'Music and fashion go together well for me as they are both very expressive. Being with Select is like getting my first real fashion job after an apprenticeship.'
Legendary model scout Tandy Anderson, of Select Model Management, added: 'Pixie is stunning. She has presence, style, an infectious personality, and has already caught the eye of various designers and photographers, from Dolce & Gabbana to Ellen Von Unwerth.
'She's a talented and successful musician and we are confident that as a model, she can enjoy similar success.'
