Beyonce at the 2007 Sports Illustrated Swimsuit Issue - Red Carpet Event in LA.
Beyonce watched what she ate before her "Sports Illustrated," cover shoot and admits she found the experience nerve-wracking. She says, "It takes a lot of guts. I'm really a shy person. "But in my everyday world, as a musical performer, I'm playing character. I had to tap that same character." (Source)
