The 42-year-old fashion designer - who recently partnered with the Estee Lauder to launch a limited edition make-up collection for Autumn/Winter 2016 - has revealed the beauty brand's "PowerFoil" mask is her "beauty must" to prepare her skin for any star studded event, which she used prior to gracing the red carpet in the South of France on Wednesday (11.05.16).

The former 'Spice Girls' band member revealed her beauty secret via Instagram on Thursday (12.05.16) with an image of her sprawled across her bed wearing a dressing gown and the skincare product. The brunette beauty captioned the post: "Cannes 2016 beauty must! @esteelauder PowerFoil mask! Au Revoir X Thank u @kenpaves @wendyrowe Love u! XVB (sic)."

And the brunette beauty, who sported a black strapless jumpsuit with contrasting white lapels, adorned make-up from her cosmetic range with the designer company, which she launched earlier this week.

She said: "So excited to debut my new #VBxEsteeLauder collection on the #Cannes2016 red carpet! X vb #recarpet #smokyeye (sic)."

The mother of four - who has Brooklyn, 17, Romeo, 13, Cruz, 11, and daughter Harper, four, with husband David, 41, - attended the bash alongside her pal Eva Longoria and Doutzen Kroes.

Eva Longoria followed suit as she sported a glittering gold foil eye shadow.

Speaking about her aesthetic during her social media takeover of L'Oréal, the brand ambassador said: "This is the madness before the red carpet."

Meanwhile, Blake Lively adorned a champagne-coloured embellished gown to the 69th film festival, which she accessorised with a number of Lorraine Schwartz diamond rings, whilst French luxury footwear designer Christian Louboutin remained by her side.

Speaking about her accessories, the mother of one - who has one-year-old son James with husband Ryan Reynolds and is reportedly expecting their second child - wrote on Instagram with her fresh manicure and glitzy jewellery, she said: "@lorraineschwartz and @ofirajewelz turned it out once again!!! Thank you!!! (sic)."
