In honor of beautiful Brazilian model Valentina Sampaio becoming the first-ever transgender woman to make the cover of the Sports Illustrated Swimsuit Edition, I wanted to put together a top ten list of the hottest Sports Illustrated swimsuit shots ever. This was a HARD list to make. It's nearly impossible to narrow down the hottest models when every single one of these women to grace the Sports Illustrated pages is a total knockout babe. Hey, maybe I just have a weakness for sexy models in barely-there bikinis. I guess I'm unique like that! (I'm kidding, of course.) Swipe through this top ten list and be careful not to drool all over your screen. As always, check out the other models here on Mr. Skin.
