After noting that Alex Rodriguez had signed up with the William Morris Agency, known for representing the world's biggest stars, I started to searching the web to see who some of those stars are.
One is Britney Spears, who used to hang out a lot with Madonna and shared a smooch with her during MTV's Music Video Awards in 2003.
Other William Morris clients include:
Gals: Serena Williams, Michelle Wie, Jennifer Lopez, Whoopi Goldberg, Erykah Badu, Queen Latifah and the Pussycat Dolls. (No, Alex, this is not a menu.)
Guys: Denzel Washington, Russell Crowe, Dwyane Wade, Kevin Garnett, Vince Young, Ice Cube, Stephen Stills, Bob Newhart, Bill Cosby, Ray Romano and the Goo Goo Dolls.
Here's one of their massive client lists and another.
