Cameron Diaz, Drew Barrymore

Djamilla Rosa Cochran/

Don't Cameron Diaz and Drew Barrymore look like they could use another pal to round out the posse? They could even hold auditions. The winner's got to be a redhead or a brunette (natural not required), or she'd blow the follicular balance. Oh, yeah, and if Cam or Drew decided to change their hair color, the new girl's gotta pick a different shade. Sorry, those are the rules if you wanna roll with these babes.
