David Letterman hosted 2013 Sports Illustrated Swimsuit cover girl Kate Upton and nine other gorgeous models last night on 'Late Night.'

The group, including Emily DiDonato, Nina Agdal, Ariel Meredith, Chrissy Teigen, Katherine Webb, Hannah David, Alyssa Miller, Genevieve Morton and Julie Henderson, graced the stage to being promoting their latest body of work.

For the first time, the yearly fashion shoot covered the entire world, with 17 models journeying to all seven continents, including African dunes and Asian cliffs.  The amazing photos were captured over a span of 10 days in December.  Florida girl Upton, 20, drew the Antarctica assignment clad only in a white, fur-lined parka and bikini bottom.

The lovely swimsuit models mentioned above will begin a seemingly endless series of appearances in order to sell lots of copies of the most popular SI issue of the year, available on newsstands now.
