Tom Cruise is to appear on 'Top Gear' as the "star in a reasonably priced car".
The motor-mad Hollywood star is due to take his test drive later today around a circuit in Surrey, which will be aired on an upcoming episode of the popular BBC Two motoring show.
The 'Top Gun' actor will also be joined by star Cameron Diaz in a lap race whilst trying out a Kia vehicle.
Tom - who owns a fleet of fast sports car and loves stock-car racing - contacted the show himself after watching the TV show at home.
The competitive star will hope to beat 'Harry Potter' star Rupert Grint who so far holds the fastest lap time for driving a Kia.
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.
The source added to The Sun newspaper: "Tom and Cameron are over in Britain for the premiere of their new movie 'Knight and Day'. 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."
