Legendary Paul Newman spent the weekend in the fast lane: racing around with Jay Leno on "The Tonight Show" and gearing up for the weekend's Toyota Celebrity Grand Prix of Long Beach -- a star-studded charity event that raised $250,000 for Newman's camp for sick children.

Governor Schwarzenegger hung out in the pit, while stars like Frankie Muniz, Karl Malone and Meatloaf raced for their favorite charities.

Patrick Dempsey, the dreamy doctor on ABC's hot new drama "Grey's Anatomy," shared a secret to his own anatomy -- keeping in shape for those sex scenes! "Now the pressure's on," Patrick admitted. "Plus, I'm getting to be middle-aged, I've got to really keep my stuff together!"

So, while Patrick's busy working out, Paul's busy recruiting his famous friends for his own charity: the upcoming Camp Hole in the Wall event, featuring Julia Roberts and as Paul told us, "Paul McCartney, Robin Williams, the Emerson String Quartet, a whole bunch of people."

It seems that when Newman wants to make things happen, he really puts the pedal to the metal.
