Whilst promoting their new flick Day and Knight Cameron Diaz and Tom Cruise managed to squeeze in a visit to the Top Gear studios.

And of course, a guest cannot appear on Top gear without competing against one another for the best lap around a track.

Tom seemed comfortable whizzing around the race course but Cameron experience trouble with her engine, waving for help midway through. Poor Cam.

To catch all the drama from the race tune into this Sundays episode of Top Gear.
