Bathing suit season has begun. The 2008 Sports Illustrated swimsuit issue hit newsstands Tuesday with model Marisa Miller adorning the cover of the annual showcase of the hottest beach bodies.

This year's sexyfest features race car driver Danica Patrick, four athlete's wives, 12 NFL cheerleaders and Will Ferrell and Heidi Klum in a special Semi Pro photo shoot. Also, body painting is back for the 10th year.

Featuring 19 models, the photo shoots took place in Israel and Russia for the first time. Other exotic locations for the steamy spread included the Cayman Islands, St. John, the Virgin Islands and Maui.

On Monday night, a three-story billboard featuring Miller's cover was unveiled to viewers of David Letterman's "Late Show."

It is Miller's seventh appearance in the swimsuit issue.
