>The 35-year-old Access Hollywood coanchor can remember when he was a kid caught up in the national hoopla over the Grease movie, released in 1978. "I had two crushes on Olivia Newton-John. One at the start when she played uptight, pink-sweater Sandy, and then the naughty, 'let's rock and roll' Sandy at the end." Sure, he fantasizes about what it would be like to tackle John Travolta's role of bad-boy Danny. But if he wanted to cast himself as a gag? "How about Vince Fontaine," the hotshot DJ? "He's such a cheeseball."
