Today’s celebrity cleavage belongs to a 20-year-old supermodel who was born in the Midwest town of St. Joseph, Michigan and was raised in Melbourne, Florida.

As a young equestrian, she competed on a national level at the America Paint Horse Association with her horse Roanie Pony, winning three APHA Reserve World Championships.

In 2008, she decided that instead of showing ponies, she would rather show off herself and made the decision to attend a casting call in Miami for Elite Model Management – she was signed by the agency the same day.

After moving to New York, she landed gigs modeling for Garage, Dooney & Bourke, and in 2010, she became the official face of Guess.

Come on guys, who is this horse riding supermodel with the amazing rack?

It's Kate Upton!

Kate is probably best know for her “Rookie of the Year” body paint appearance in the 2011 Sports Illustrated Swimsuit Issue.

Since then she’s modeled for Beach Bunny Swimwear, Victoria’s Secret and Esquire as one of the “Women of Summer.”

Most recently Kate appeared wearing a leather-clad bikini while performing the “Cat Lady” in a viral video directed by Terry Richardson – landing nearly 750,000 views in less than 24 hours before being temporarily removed for violating YouTube’s rules for sexual content. Whoopsies!

Incidentally, Kate Upton does not violate any of our rules for sexual content… not one!
