What's a high school without cheerleaders? These are the stars so bubbly, so pretty, so perky, that it's almost annoying -- and yet, their enthusiasm is contagious. Cameron Diaz, with her enviably buff body, contagious laugh and irresistible smile, is clearly the head cheerleader. Rounding out the squad are Kate Hudson, Jessica Simpson and Eva Longoria Parker. And while it's not an official requirement, all of the Hollywood High cheerleaders have dated high-profile athletes: Longoria's NBA hubby Tony Parker, Simpson's football-playing boyfriends past and present, and Hudson and Diaz's shared love interest, Alex Rodriguez.
