Top Supermodels Strip Down for Pirelli Calendar

ET is with supermodels Miranda Kerr, Karolina Kurkova, Alessandra Ambrosio, Helena Christensen, Alek Wek and Isabeli Fontana as they shoot for the prestigious Pirelli Calendar's 50th Anniversary!

The calendar -- which has become a mark of distinction for the models chosen, as well as the famous photographers who shoot them -- is famous not only for its limited availability (it's only given as a corporate gift to a restricted number of important Pirelli customers and celebrity VIPs), but for having legends like Cindy Crawford, Naomi Campbell, Heidi Klum and Gisele Bundchen previously pose for it.

"I remember seeing some Pirelli calendars in the '80s. I thought they were super-cool and ... glamorous," Kerr, who's quickly become one of the industry's most recognizable faces, tells ET. "They're also sexy and chic and they're current to the time -- to the year that they're shooting. But they're also all about celebrating women -- so am I -- and I'm just really honored to be a part of it."

What also makes the Pirelli Calendar so unique is that such high-profile models get to shoot together, which Kerr confirms is as fun as it looks.

"On the beach yesterday, it was pretty hot," she smiles. "I was standing next to Helena for most of the day, so I had a good day at the office."

"I think it's a great group of women -- all ages, all different colors and mentalities and backgrounds," Kurkova adds. "I think that makes the pictures really special. We've all done Pirelli calendars more than once, and it's nice to be here -- all of us together -- for iconic, timeless, classic pictures ... you just really do have a great mix of women and different looks, and styles, and personalities and expressions and we really represent women and empowering women. ... In these pictures, it's not about the clothes we wear, the makeup and hair, it's just about seeing us as women and our experiences, and I think that really comes through in the pictures."
