The bodaciously sexy 2013 Sports Illustrated Swimsuit Issue cover model, Kate Upton, was a guest on Late Night with Jimmy Fallon last night to pimp the brilliant magazine, and she looked red hot from head to toe and ridiculously cleavagy while doing so… sweet baby Jesus! Now that’s how you promote a bikini magazine, eh? Hell, that’s how you promote anything! Hands down some of the best cleavage shots of the decade. And if you think that the pictures are something to drool over, then wait until you see everything in shwingtastic motion in the video bellow. Enjoy!
