The stunner, aka Scary Spice, stripped off to bra, knickers and stockings to display the new collection.
Keeping in sync with the burlesque theme, the 33-year-old mum posed with vintage props including a fan, elbow-length satin gloves and beaded necklaces.
"Burlesque is all about embracing and celebrating your body. The shoot was fantastic and I felt every inch the burlesque star," The Daily Star quoted her, as saying.
"A girl's gotta have great lingerie, but it's also all about the wink and the tease that goes with it. Modelling lingerie is really empowering and it was fantastic to get in character. The new Ultimo collection is super-feminine, with lashings of elaborate detailing, luscious colours and sexy fabrics. I just love it!" she added.
The shoot even ties in with her new Las Vegas burlesque extravaganza Peep Show, where she plays mistress of ceremonies Peep Diva.
It kicks off on March 30 at the Planet Hollywood Resort and Casino.
