Princess Anna packs a mean punch! Or, in this case, a serious slap.

During the premiere of Kristen Bell's new movie The Boss, Kristen slapped a reporter who got handsy on the red carpet.

All I have to say is "you go, girl"! That reporter completely deserved to be slapped. I mean, the dude was clearly drunk, he wasn't acting professionally, and he had no right to grab her. I hope he's embarrassed.

If you didn't know not to mess with Kristen Bell, now you do. She sent that fool flying over the barricade!
