There's nothing like seeing a "Sports Illustrated" swimsuit issue when the swimsuits aren't really swimsuits at all.  Painting bikinis onto naked models has done well for the magazine because everybody wins. Sales of those particular issues explode, as do the guys who buy them.  But it's even better when there is nothing left for the imagination.

Our guess is that it was an accident, but either way... who cares!  "SI" posted an old picture of the super-sexy Kate Upton with a painted-on bikini and they "forgot" to airbrush or block out the entrance her "lady tunnel."  That's right... you can see Kate's "whispering eye" winking at you!
