Timeless beauty: Agent Provocateur co-founder Serena Rees wanted Catherine for the campaign because of her incredible presence. - CRIENGLISH.com

Model Catherine Bailey joins Kate Moss, Maggie Gyllenhaal, and Daisy Lowe as the latest celebrity beauty to strip off for cult lingerie brand Agent Provocateur - but at age 46 years old - she might just be the oldest.

At 46, Catherine Bailey has lost none of her charms. She talks about her husband, her body and why she loves being naked.

Catherine, who is married to celebrated photographer David Bailey, is seen in racy pictures which were shot in a country house outside Oxford, dressed as a scantily-clad lady of the manor, in charge of two naughty French maids - one of whom is Pearl Lowe's daughter 18-year-old daughter, Daisy.

Dressed in a mix of the lingerie company's trademark boudoir-style underwear, including a peephole bra, sheer body, and stockings, the mother-of-three, smoulders in the raunchy shoot, which despite her advancing years, reveals her still incredible body.

Bucking the trend for fashion companies to use ever younger models, Serena Rees, who co-founded the celebrities favourite underwear store in 1995, revealed why she chose the forty-something as one of the four faces of the new campaign.
