The Russian beauty who's Cristiano Ronaldo's girlfriend only knew she made the cover at the "The David Letterman show".
No chance for anyone to even take a glance that article about "Kate the Great"!
In fact, if Irina Shayk skeezes a little more, Kate the Great will fly off the cover ...
I can only imagine the phylosophical conversations Irina Shayk has with boyfriend soccer player Cristiano Ronaldo...
Here's the official presentation of Irina Shayk as the cover of Sports Illustrated Swimsuit 2011. Enjoy!
