Cristiano Ronaldo‘s 25-year-old Russian girlfriend, Irina Shayk, is this year’s Sports Illustrated Swimsuit edition cover girl. Irina found out she was the cover girl during a taping of 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.”

Irina is not new to the mag. After winning the “Supermodel 2004” Chelyabinsk beauty pageant, Irina pursued a career in modeling. In 2007, Shayk debuted in the Sports Illustrated Swimsuit Issue, and has appeared in each annual edition since.
