Robbie Williams Karts Off Cameron Diaz

The Sun reports Cameron Diaz went on a go-karting date with Robbie Williams, in a move that will likely infuriate *NSYNC star Justin Timberlake, who is touring the U.S. “They bumped into each other in the bar and decided it would be fun to go karting,” a source close to Robbie revealed. “They headed off to a posh track in the Spandau area of the city and had a great time. They both have very bubbly personalities and bounce off each other. I don’t really know if there was much romance involved but who knows what might happen?”
