DIVA DIAZ SCRUBS DIRTY JOHN

In Boston lensing “Wichita” on location, germaphobe CAMERON DIAZ freaked when she laid eyes on the bathroom in her dressing trailer, fuming it was filthy – even though crew members thought it looked just fine.

Rolling up her sleeves, Diva Diaz demanded rubber gloves, a bucket of hot water and disinfectant – then dropped into doggie position and energetically rub-a-dub-scrubbed until the room was sparkling.

And get this: She even kept the cleaning supplies for later.
