Rocker Tom Petty has promised his worried wife he won't get back behind the wheel of his car after making a spectacle of himself by literally crashing Adam Sandler's wedding. The RUNNING DOWN A DREAM singer was distracted by silver weather balloons Sandler sent up to thwart paparazzi trying to get wedding shots from helicopters - and he rear-ended a guest. Petty reveals he now only drives when he absolutely has to after promising his wife DANA he'll hang up his keys. He explains, "The last two times I drove I had accidents. It just came down as a rule that I am not allowed behind the wheel. I like to drive, but after that last time, I knew I had scared my wife. "As I was coming back (from the store) I saw three enormous silver balls floating in the sky... People were pulled over to the side of the road pointing. "I ran in the house and yelled to Dana and her friend, 'Get in the car, you have got to come see this...' I had them convinced that they (balloons) were UFOs. "When we got a lot closer we could see that there was a thin wire attached to them and that they were only balloons... Right when I realised this, I go to turn the car around and I crashed into an oncoming car and nearly killed two people." Frantic Petty then pulled off the road and into Sandler's wedding party - where he was swarmed by the paparazzi.
