If you've never heard of Kate Upton before, get ready to become better acquainted.
The 19-year-old graces the cover of the 2012 Sports Illustrated Swimsuit Issue, which "The Late Show with David Letterman" unveiled Monday on a billboard across from the Ed Sullivan Theater.
Upton and nine other models from the issue also stopped by Letterman's late night show to help him deliver his top 10 list, which focused on why this year's Swimsuit Issue is the best ever.
One cryptic reason was that the magazine apparently includes ten models, but only nine swimsuits, while another was, "It's not in 3-D, but it looks like it is."
Cover star Upton offered this enticing reason: "The art department was able to airbrush my mustache."
Clearly this is a woman with a sense of humor, and we'll likely get to see more of it when the 19-year-old returns to "Late Show with David Letterman" tonight for an interview.
In the meantime, watch the clip of Upton hitting her dougie, which turned the model/actress into something of a viral video star:
Upton, who had a role in 2011's "Tower Heist," will also appear in the Farrelly brothers' "Three Stooges" in April.
