Kate Upton Graces The Cover Of Contributer Magazine

She went from a relatively unknown model to a household name when she was named the covergirl for Sports Illustrated's prestigious Swimsuit issue earlier this year.

But now Kate Upton has upped her game even further by leaving the string bikinis at home to go completely nude for the new issue of Contributor magazine.

The stunning blonde model is seen showing off her world-famous curves as she reclines on a king-size bed in the sexy shoot.
