No offense to pets and National Pet Day, but April 11th is really only special because it’s the day that Brazilian supermodel Alessandra Ambrosio was born. As you can see in our Celebrity Yoga Pants Butt tribute, Alessandra looks fantastic out in the wild. The reason she pulls in the big bucks, though, is because her photoshoots are to die for. We figured that to celebrate the wonderful woman’s 31st birthday, we’d gather her 31 hottest photos. The decisions were certainly tough, but that’s we get paid the big bucks. Check out one of the hottest women on the planet below.
