They still haven't found a recipe for coffee at Casa de Britney, so Hollywood's biggest mess hit up Starbucks in glamorous Sherman Oaks, Calif., last week.

That's when Britney took off her Weaveguard© headband - and even her new little dog, London, seems traumatized by what she exposed to the world. Ack!

Celebrity news photographers snapped the hair-iffic pop star as Britney Spears showed off a complex construction of braids and what looks like some type of epoxy...

Nice hair, Britney Spears, you wreck. Straight out da trailer, y'all!

The walking train wreck also wore a tube top, a bitten-up manicure, some Elvis / Tom Cruise style sunglasses to compliment her newest accessory - teacup Yorkie puppy London.

No photographers were injured on the scene. And that's good, because you never know when dogs are just gonna go nuts. Ving Rhames knows what we're talking about.
