Sports Illustrated Swimsuit 2011 Model Irina Shayk Appears on David Letterman (VIDEO)
David Letterman revealed that Russian model Irina Shayk is the 2011 Sports Illustrated swimsuit cover model on Late Show Monday night.
It's her fifth appearance in the issue, but her first cover.
"There were 10 models there to do the Top 10 List, and nobody knows until the last minute who the cover will be," Shayk (who is dating soccer star Cristiano Ronaldo) said. "And then I saw it, and I couldn't believe it."

The news was accidentally revealed earlier when an office worker snapped a quick cell phone photo of a billboard of Shayk being taped for a Letterman segment.
