Irina Shayk was unveiled as the newest Sports Illustrated Swimsuit Edition cover girl yesterday on The Late Show! The Russian beauty and girlfriend of Cristiano Ronaldo wears a pink and yellow bikini on the front of the issue, which also features SI favorite Brooklyn Decker. Irina was up bright and early this morning to chat about her exciting news on The Today Show as well. She's following in the footsteps of several past cover girls, like Tyra Banks and Bar Refaeli, who have gone onto great success. It's a big deal for Irina to land the honor, but she's still a relative unknown here in the US. Tell us what you think about Irina as the pick for the 2011 edition — is she a good choice or do you still wonder who she is?
