Any time you get a pet-related cause benefit going, you're going to get some supremely good looking celebrities out for the gala or party or spay and neuter party. The Human Society is the biggee and they celebrated their 60th anniversary with a full and loaded cast of sextastic hotties at a benefit to raise money to help out our furry little friends.
While there were numerous sextastic ladies decked out for the event, Joanna Krupa and her super duper see-through dress surely made an impression, as did the massive sideboob revealing little number worn by Twilight brunette darling Christian Serratos. I'm not sure if the animals noticed all the effort these ladies put into showing off their sensational boobtastic, but if they did, you might've heard some happy barks and purrs in honor of the exhibitionist delights. Oh, to be a hairy little beast in either of these two ladies' arms over the weekend. That is the position of honor. Enjoy.
