Holden, 40, who is the lone female judge on 'Britain's Got Talent', was photographed stretched across a bed naked, with just a pair of black TrimSole flip-flops, and a sheet to hide her modesty.
With her short hair curled and lashings of red lipstick, the former 'Cutting It' star channels the spirit of the late Hollywood icon Monroe.
Holden officially launched the new campaign for the Spring/Summer 2011 collection at London's historic Criterion restaurant in Piccadilly.
Footwear from the TrimSole brand comes with a unique Trim-Tech sole to subtly shift your centre of balance to make your legs work harder when you walk.
"I'm convinced my bum is already more pert after wearing the shoes all day," the Daily Mail quoted Holden as saying about the range.
The new collection features not only traditional colours like black and silver, but also animal-prints for the more flamboyant fashionista.
TrimSole footwear starts from £24.95 and is available online.
