Tom Cruise and Cameron Diaz launch attack on the Stig in bid to reveal his secret identity

Cameron Diaz and Tom Cruise joined Britain’s mission to discover the Stig's identity while filming their upcoming episode of Top Gear.

The Hollywood actors tried to wrestle his helmet off in a bid to unlock his secret identity, but despite their efforts, not even Tom Cruise could solve this mystery.

The part man, part machine driver, famed from the BBC2 show, came to Diaz’s rescue when her Kia conked out during her circuit at the Top Gear base.

Mystery not solved: Tom had given up trying but Cameron still tried to wrestle the driver - unsuccessfully though

But instead of thanking her aid, the 37-year-old cheekily took a firm grip of the driver’s headgear and tugged unsuccessfully, along with her Knight and Day co-star Cruise.

The Stig stood there with his arms folded, knowing that the actors had no hope of winning their battle.



Cruise, 48, described his Top Gear experience as ‘fun, very fun’, at the London premiere of his latest film last night.

‘I like fast cars and motorcycles – I’ve always loved them since I was a kid,’ he said.

While Diaz gushed: ‘We did timed laps. It’s very exciting – we know the score and we want to tell everybody, but we can’t because we want them to watch the show.

‘I love speed. What I love about it is that you have to live in the moment and I love just being in the moment.’

It has been previously revealed that the BBC employs at least four drivers to don the pristine racing whites, thought to be former racer Ben Collins and formula one driver Julian Bailey, while the others still remain a mystery.

Lap scores: The stars are told their lap times, but won't reveal their true scores until the BBC2 show airs

Before her wrestle with the Stig, Cameron Diaz took to the racing track, but dramatically broke her car during a high-speed race.



A shaken Cameron Diaz waved for help on the track, where the actress and Cruise were pitted against each in a bid to get the best lap time.

After receiving some initial training from the mysterious Stig, the actress took to the track, but apparently hadn't mastered her clutch control.

While going round the circuit, the motor came to an abrupt stop with the gear box making a terrible crunching sound.

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.



The driving expert duly came to her rescue in his white sports car before Diaz's car was worked on by mechanics.

Cruise was also on the race course in Surrey today taking part in the 'Star In A Reasonably-Priced Car' feature.

Viewers will be able to see the full drama on Sunday's episode of Top Gear on BBC2.

No doubt they will be hoping to trounce Harry Potter star Rupert Grint, who has set the bar with his speedy lap.

However, it is unclear whether Diaz will get to take her lap again after not completing the course.
