The 23-year-old Brit posed for the fashion house's creative director Hedi Slimane for the brand's fall 2016 styles, dubbed La Collection de Paris.

"Cara and Hedi have worked together many times over the past four years," a Saint Laurent spokesman wrote in a tweet on Wednesday (30Mar16).

The black-and-white images feature the sultry model-turned-actress in a heart-shaped fur coat, a black tuxedo, and a black, strapless sequined dress.

Slimane also recruited 69-year-old Birkin for his new Saint Laurent Le Smoking campaign.

The veteran French star was photographed in the brand's iconic tuxedo at the Yves Saint Laurent Couture House in Paris.

Meanwhile, the new YSL campaign comes at a crucial point in Cara's career - she has just been immortalised in wax by artists at Madame Tussauds and her eerie lookalike was unveiled in London on 23 February (16) as part of an exhibit dedicated to London Fashion Week.

She will also be seen in the much-anticipated comic book blockbuster Suicide Squad this summer (16).
