Heidi Klum Fools Around with Will Ferrell in the 2008 Sports Illustrated Swimsuit Issue

Proving she's still got everything we love about her, Heidi Klum gets back into her bikini after countless appearances in the Sports Illustrated Swimsuit Issue, and she brought Will Ferrell along for the ride. This time around, Heidi brings back the sexiness of the Swinging Seventies to promote Will's new movie Semi Pro, and shows off her sense of humour at the same time. If the movie is as entertaining as these pictures, I'm totally there.

Don't forget to check out Marisa Miller topless on the cover of the 2008 Sports Illustrated Swimsuit Issue, along with our 2008 Sports Illustrated Swimsuit Issue Round-Up post, and of course, the SI.com Swimsuit site for more Heidi Klum, and even more bikini awesomeness.
