Birthday Boobs - Kate Upton - See-Thru in Photoshoot

Happy 21st birthday to the voluptuous Kate Upton. Personally, I'm hoping she spends her 21st like millions of other American women spent theirs: getting trashed and flashing her boobs. Okay, so I don't know for sure that millions have done that, but I'm sure quite a few have!In any case, enjoy these awesome see-thru shots of the birthday girl. Happy birthday, Kate Upton!More pics after the jump...
