We're not sure what the occasion is, but Sports Illustrated has been sharing tantalizing #throwback videos of old shoots featuring its hottest swimsuit supermodels.
This time, the early work of the always amazing Kate Upton is up for review. And to the surprise of absolutely no one, Kate's stunningly all-natural talent passes every bikini beauty test in the book.
The bodacious blonde, who began a long-running relationship with SI in 2012, wows in this clip showing her enjoying an outdoor shower at some luxurious tropical resort.
Previously, the good people at SI shared another #throwback video of Kate busting a move on the beach that can be seen here.
But she sizzles in just about every scenario you put her in. Just take a look at some of her finest photos below.
