Chris Evans has reportedly stalled filming for 'Top Gear' after realising he has trouble talking and driving at the same time.
The BBC motoring programme has been dealt yet another blow after the new host, who has taken over from Jeremy Clarkson, Richard Hammond and James May in a new three-year deal, failed to "master the art" of multitasking.
A source told The Sun newspaper: "Chris is really struggling to master the art of driving and talking to camera, which is crucial. He is in a massive sweat about it because he often ends up fluffing his lines.
"The professional drivers are doing a lot more to cover for him and the camera crew are getting frustrated."
The embarrassing issue is just the latest in a long line of setbacks for the forthcoming series after executive producer Lisa Clark announced three weeks ago she was quitting her role - five months after she was brought in to take the reins.
Alex Renton, who has been series editor on the hit show for 10 years, will take over as producer on an interim basis to ensure there are no issues with the production schedule.
A new executive producer will be announced in due course.
'Top Gear' is set to return to screens on May 8.
