Who says pretty girls are shallow? Not these beauties, who are doing their part to help the areas affected by the Gulf Coast oil spill! For the last three years, the Philadelphia Eagles cheerleaders have posed for their annual Eco-Sexy calendar, with the proceeds going to earth-friendly causes. This year, the squad is wearing swimsuits made from recycled materials, with ten percent of the proceeds being donated to benefit the nonprofit Gulf Restoration Network. The calendar went on sale Thursday. Good job, girls!
