Pirelli calendar model cast revealed

While German designer Karl Lagerfeld is shooting the iconic Pirelli calendar in Paris this week, a picture of the participating models has been leaked via Twitter.

The photo posted by Brazilian supermodel Isabeli Fontana - which has since been removed after it appeared on the Brazilian Quem website - showed herself alongside her colleagues including Magdalena Frackowiak, Heidi Mount, Natasha Poly, and Bianca Balti.

According to blogs such as Fashionologie, Lara Stone and Julianne Moore are also rumored to be part of the cast.

Pirelli's calendar is considered the most exclusive pin-up calendar of the world, since it cannot be bought and is only distributed to the brand's clients and VIPs in very limited quantities.

Lagerfeld joins the ranks of star photographers Patrick Demarchelier, Bruce Weber and last year's Terry Richardson - currently the center of a controversy surrounding his provocative images and shooting 'methods' - who have all shot for Pirelli.

But the Kaiser's calendar will probably look different than past versions: he is reportedly working in his Paris studio because "it's too obvious to have a beach setting."
