E! Online got a behind-the-scenes look at the Sports Illustrated swimsuit shoot, which meant traipsing along the beach with Hilary Rhoda, Julie Henderson and Damaris Lewis. Fun! The cover girl has yet to be revealed -- it'll be debuted on "The Late Show With David Letterman" come February 14, but we have to say, we like Henderson's attitude. She told the cameras, "It's nice to roll around in the sand and be all grimy...like a sugar donut, almost."
