11. Nia Long
Most Memorable Role: Brandi in Boyz in the Hood (1991)
In her films, Long is the ultimate ride-or die-chick, sticking by an unemployed Ice Cube in Friday and a convicted Mekhi Phifer in Soul Food. And in Big Momma's House, she takes back Martin Lawrence, even after he poses as her overweight grandmother. Now that's a girl who's always down for her man.
