TMZ Catches Maria Shriver Driving with Cellphone 3 Times, Schwarzenegger to take 'Swift Action'

Her husband may have signed the no driving while holding a cell phone law, but the message apparently hasn't hit home for California's First Lady Maria Shriver.

TMZ earlier today posted two photos--one from this Summer and another from this weekend--of Shriver on a cell phone while driving. In response, Schwarzenegger this afternoon tweeted to TMZ's Harvey Levin: "Thanks for bringing her violations to my attention. There's going to be swift action."

But soon after his tweet, Shriver was once again jabbing on the cell phone while driving in Brentwood. Of course, TMZ posted it, along with a video, online: "while Maria was illegally yappin' away (the third time she's been photographed doin' it) she saw our cameraman catching the illegal activity on tape -- and that's when she dropped the phone in an attempt to cover it up!"
