Actually, her hair doesn't look that bad, but when we snapped Cameron Diaz on the set of Bad Teacher in Los Angeles yesterday, she looked like she was having a blast playing a mega bitch!

Cameron's character is a junior high school teacher who gets dumped by her sugar daddy, and it seems like she's taking her role rather seriously. We're actually pretty excited to see this...too bad we've got to wait until 2012 to see it!
