Irina Shayk gets 2011 SI Swimsuit Edition cover

Irina Shayk has risen to the top of the modeling profession.

The 25-year old Russian is this year's Sports Illustrated Swimsuit edition cover girl, an honor she first discovered herself yesterday at a taping of The Late Show with David Letterman.

"There were 10 models there to do the Top 10 List, and nobody knows until the last minute who the cover will be," Shayk said. "And then I saw it, and I couldn't believe it."

This might explain why Irina Shayk is suddenly a Trending Topic on Twitter. Or maybe this is why....

@theirishayknews Irina Shayk is actually the first russian model, who is on the cover of @SI_Swimsuit :))
