Help! Cameron Diaz waves for assistance today after coming to a grinding halt. She is believed to have wrecked the clutch during filming for Top Gear in SurreyA shaken Cameron Diaz waves for help after she dramatically broke her car during a high-speed race.
The actress was filming with her Knight And Day co-star Tom Cruise for Top Gear this afternoon where the pair were pitted against each in a bid to get the best lap time.
After receiving some initial training from the mysterious Stig, the 37-year-old actress took to the track, but apparently hadn't mastered her clutch control.

Diaz, who is promoting her new movie in London tonight, then jumped out of the vehicle - a red Kia cee'd - and waved at the Stig for help. It is part of the Stig's role to train the celebrity drivers for the 'Star In A Reasonably-Priced Car' feature.
