California's first lady could see her car insurance premium rise after a celebrity website published photos of her holding a mobile phone while driving - breaking a law signed by her husband.
Arnold Schwarzenegger, governor of California, published a note to the founder of the website, TMZ.com's Harvey Levin, thanking him for publishing the photos.
It said: "Thanks for bringing her violations to my attention. There's going to be swift action."
His spokesman Aaron McLear later said that by "swift action" Schwarzenegger meant he would ask his wife not to hold the phone while driving again.
TMZ.com posted two photos showing Maria Shriver holding a phone to her ear while driving, one said to be from the weekend and the other from July. It later posted a video showing the same thing.
Using a mobile phone while driving became illegal in California in July 2008. In Los Angeles County, people breaking the law can be fined around £58 for the first offence and £126 for subsequent offences, meaning Shriver would owe £184 if she had been caught by police.
The first lady's office refused to comment on the pictures.
