Photo Finish: Kristin Cavallari vs. Amanda Bynes

In this day and age, you're just not "Hollywood" if you don't have fake hair (and a DUI conviction). Well, the newly 21-year-old Kristin Cavallari and Amanda Bynes have not gotten popped for DUI (that we know of), but both of these cuties have got some hair extensions all right! Nope, those blonde blocks aren't all real.

Doesn't mean they're not attractive, of course. Or are they? Tell us, who do you think is hotter, hair extensions and all - Amanda Bynes or Kristin Cavallari?

Somewhere, Heidi Montag is already thinking of when she can fit hair extensions into her busy schedule of staging bikini pics and talking $h!t about LC.
