In a brand new ad, the Hollywood actress writhes on the floor, only scarcely covered by a satin sheet, to promote Lancôme's L'Absolu Nu (French for "absolute nude") lipsticks.

Winslet, who recently debuted a peroxide blond pixie cut in British Vogue, is still sporting her signature soft locks in the ad, which was shot by star photographer Mario Testino.

Actresses are seemingly less and less prudish in their beauty ads: just recently, Italian luxury house Bulgari released a campaign fronted by an almost nude Kirsten Dunst for its new fragrance Mon Jasmin Noir.

Lancôme's L'Absolu Nu lipsticks ($29 each) come in 12 different colors that are a bit lighter and, thanks to mother of pearl fragments, more sparkly than the brand's L'Absolu Rouge collection.
