Kate Upton, actress, 2012 Sports Illustrated swimsuit issue cover model, and at one time Esquire's "Woman Of The Summer" has just turned 20.

Upton has had quite the expanding profile as a model lately, which has led to her picking up some acting gigs in such movies as Tower Heist and The Three Stooges (we'll forgive her for that one). Also, you just have to respect a woman that did "The Dougie" during a Los Angeles Clippers game ... yes, that went viral.

The following photos are the epitome of NSFW (in case you plead ignorance, it stands for "Not Safe For Work" -- but, hey, it's the weekend!) Celebrate the model's 20th birthday by scrolling through some of her best work!
