It's hard to believe, but supermodel Gisele Bundchen celebrated her 30th birthday yesterday. As she celebrated turning the big 3-0, her latest ad campaign for Roberto Cavalli was unveiled. The Autumn 2010 photos show Gisele posing in a fair amount of animal print in the desert next to burning bushes. Gisele isn't the only one celebrating, Cavalli is also as this season marks 40 years of designing for the Italian. What do you think of this ad campaign?
