Margot Robbie turns up the heat for Calvin Klein

Everybody's favourite blonde positively steams up the screen in her first major advertising campaign which was released just hours ago.

In the risque ad for the new Calvin Klein scent Deep Euphoria, Margot (and a lover, actually possibly two or three) smoulders her way through several scenes.

The fragrance Margot is the new face of is described as a modern floral chypre - that is, a blend between the two fragrance 'families'. A chypre, in case you're not across the term, is a warm, dry scent based on a collection of woody mossy accords. And you know what a floral fragrance is. Blend the two and you're looking at (well, smelling anyway) something very glamorous yet terribly seductive too.

Deep Euphoria is the third in the hugely successful Calvin Klein Euphoria family. It's creators have declared it to be the most daring and sexy so far. And if this ad is anything to go by then we're guessing that's 100 per cent correct.
