When the likes of Elle Macpherson, Bar Refaeli, Laetitia Casta and Rosie Huntingdon-Whitely appeared on Louis Vuitton's A/W10 catwalk, working their big pouffy skirts and womanly curves to a soundtrack from 1950s Bardot movie And God Created Woman, it seems the music was a little in-joke between LV designer Marc Jacobs and one of his models.
Because Casta is about to explode onto the silver screen playing Brigitte Bardot in the forthcoming 'Serge Gainsbourg, Vie Heroique', based on the life of the much-idolised French singer who had a short but turbulent love affair with Bardot, before marrying Jane Birkin.
While there is currently much excited chatter about former lingerie models appearing on the catwalks, Casta has been there and done that already; she starred in L'Oreal's tv and print ads, and was a Guess jeans girl/Pirelli calendar star/Victoria's Secret angel, before moving on to front mega campaigns for Chanel, Dior and Miu Miu.
And now, after a few gentle forays into acting - she was, brilliantly, the love interest for Gerard Depardieu's Obelix (I promise we're not making this up) in the French language live-action film Asterix and Obelix vs Cesar - Casta has now landed the perfect role, as the ultimate blonde bombshell.
And as you can see from the just-realised film stills, the formerly chesnut-maned mother-of-three pulls off BB's peroxide pouty looks remarkably well.
We'd love to know who else was up for the role - Claudia Schiffer ? Lara Stone ? Georgia Jagger? - but Casta has a trump card advantage over her sex kitten rivals - having long been something of an official national treasure in France. In 1999 Casta won the honour of being France's Marianne, (a kind of annual beauty contest to choose the woman who best symbolises the French Republic). Previous Mariannes have included model Ines de la Fressange, Catherine Deneuve... and Brigitte Bardot herself.
