Karl Lagerfeld is a man of many talents: fashion designer, producer, weight loss guru…ice cream sales man? Yes the uber stylish Sir Lagerfeld is heading Magnum Ice Cream’s new campaign. They are filming in Paris as we speak and sources have it that Rachel Bilson has been seen on set looking AMAZING. Her Black Swan inspired look with tiara, tutu, and nude pumps should make for an interesting ice cream add. Baptiste Giabiconi, Langerfeld’s muse, was also near set but we can’t confirm if she’s in the campaign or just there for the ice cream.
