Kristen Stewart showed up at the Late Show With David Letterman today as a redhead. Her new look is short, edgy, bright, and it's quite the deviation from the brown shoulder-length style she rocked before. She must've switched up the hue over the weekend, because she had brown hair just a few days ago at The Twilight Saga: Eclipse premiere in Los Angeles. 'Tis the summer for lots of bright hair colors, just as we suspected!

+ How do you like Kristen’s new color — do you prefer her as a redhead or brunette?
