There's something about seeing a woman's belly. It doesn't matter if she has washboard abs or a big ass gut—if we see bare midriff out the corner of our eye, we'll look anyway. It's kind of like the rush you get when you catch the smallest of nip-slips. GOTCHA!

All that aside, crop tops are a huge trend for girls this summer. And lucky for us, hot celebrities are wearing them out and about for us to see. Let's play who has the best belly button!
