Head Over Heels for Kristen Stewart

Attention all you crazy Edward Cullen fans -- this video won't get you any closer to the bloodsucking bad boy, but you can at least take joy in knowing the girl he does sink his teeth into totally ate pavement on a movie set.

Though Kristen Stewart was filming as Joan Jett in "The Runaways," she totally pulled a Bella Swan -- by clumsily hurling herself into the sidewalk.

Trust us, this wasn't in the script.
