Hollywood stars Tom Cruise and Cameron Diaz will both appear on Top Gear, as the ‘star in a reasonably priced car.’

Mission Impossible star Tom and Something About Mary actress Cameron will each go for a spin around the track in a Kia cee’d for this Sunday’s show.

Tom and Cameron – in the UK to promote their new movie Knight and Day – are due to complete the lap in Surrey today, reports The Sun

A show source said: “We’ve had some big names tearing around in our reasonably priced car, but Tom has to be up there as the biggest.

“And the amazing thing is his people contacted us.”

Tom, who starred in 1990 stock car movie Days Of Thunder, has a fleet of sports cars and is a fan of stock car racing.

The source added: “Tom knew we were filming so asked if he could give the old Kia a whirl.

“Cameron was up for it too so we’re getting two A-list stars for one show. Jeremy Clarkson and the boys couldn’t be happier.”

Harry Potter star Rupert Grint is currently the fastest star to lap in the Kia on the BBC2 show.
