Kate Upton Talks Sports Illustrated Swimsuit Cover, Role In 'Three Stooges' On 'Late Show With David Letterman' (VIDEO)

Kate Upton spent Monday night at "Late Show" (Weeknights, 11:35 p.m. EST on CBS) watching the unveiling of her on the cover of the 2012 Sports Illustrated Swimsuit Issue. She returned Tuesday night to talk about this boost to her already rising career, as well as her forays into the world of acting. Particularly, she said she enjoyed working with the Farrelly brothers on their upcoming film "The Three Stooges."

"It was so much fun," she said, before realizing that of course David Letterman was going to have a photo. Much like her modeling work in bikinis, this picture featured Upton in a skimpy nun-inspired swimsuit alongside the Stooges themselves.

"Which one is you?" Letterman quipped, before asking her if acting was a direction she'd considered for the future of her career. "The lifespan, the earning potential of a professional athlete is sometimes limited, and the same is true with supermodels," he said.

"I have a few more years in me yet," the 19-year old supermodel retorted. "Don't cut me out so soon!"

Kate Upton can be seen on the cover of the 2012 Sports Illustrated Swimsuit Issue, available on newsstands nationwide. "Late Show" airs weeknights at 11:35 p.m. EST on CBS.
