Think fraternities and sororities are just for common people like us? Think again. Some of the hottest stars in Hollywood went Greek back in their college days. For instance, before Sheryl Crow "soaked up the sun" as a big-shot singer, she pledged her allegiance to the sisterhood of Kappa Alpha Theta at the University of Missouri-Columbia. Ashton Kutcher probably Punk'd more than a few freshmen during his days as a Delta Chi. And long before Melrose Place, Heather Locklear called Chi Omega home. Find out whether you're chapter-president material or still a pledge by matching these celebrities to their Greek houses before time runs out.
