Idol David Cook Rocks the Jocks

American Idol, national anthem, seeks a logical fit.

David Cook did his best to rock out the "Star-Spangled Banner" at the NBA Finals last night, performing during game three in the Lakers-Celtics series.

And while Simon Cowell wasn't there to critique the performance, a bunch of even more intimidating big names were, including David Beckham, Tobey Maguire, Jack Nicholson, Hilary Duff, Kristin Davis, Kanye West, Fergie, David Arquette, Dustin Hoffman, Andy Garcia, Steven Spielberg, Sylvester Stallone, Eddie Murphy and Cook's Idol-powered girlfriend Kimberly Caldwell. (She was apparently returning the favor—he was there to lend moral support to her rendition of the national anthem at a Dodgers game last week.)

Forget Hollywood week, Cook just made it through Hollywood night.
