The Britney Spears head shaving tattoo wearing crazy train rolls on. Just when you think it couldn't get it any weirder - Britney Attacks!

A desperate Britney was photographed using an umbrella to hit a car outside the home where her ex, KEVIN FEDERLINE, is reportedly staying. The photos reveal a furious Britney, dressed in white shorts and a hooded sweatshirt, repeatedly striking an SUV with an umbrella.

x17online has a video as well (thanks guys). She's a militant Mary Poppins! The photographer even got a whack across the back.
