It’s a pretty crappy weekend, weather-wise, for most of the country, so how better to warm things up than with this year’s Sports Illustrated Swimsuit Issue models? Gaze upon these voluptuous vixens rolling in the sand on tropical beaches and forget that your car is buried under three feet of snow.

2011 SI cover model Irina Shayk scandalized some media types with her appearance on “Chelsea Lately” last week. No, it wasn’t anything the Russian supermodel said—it was the photos revealing that she hadn’t shaved her legs! Irina’s tight red mini skirt couldn’t conceal the fine film of fuzz covering her long, lean gams.

So far, there’s been no explanation coming from Irina, which makes you wonder if she just “lets herself go” in between modeling jobs, but the supermodel is picture perfect in these shots from the SI Swimsuit Issue! See more of Irina after the jump, and go to SI.com for all of her sultry shots from this year’s issue.
