... On a Horse

Here's video of Kate Upton topless ... all the way topless ... on a horse.

You're welcome.

Now for some background: The video was taken during a recent modeling shoot ... Kate begins the session in the hopes she can keep her breasts covered by her hand -- but quickly realizes, there's just no way.

Eventually, she lets the girls loose ... and it's everything we always hoped it would be.

Unfortunately, we can't show you the completely uncensored version ... but we can show you video of our staff watching the uncensored version for the first time -- and it's pretty damn hilarious.
