The joke was on Michael McIntyre after his son's computer branded him 'overweight'.
But the floppy-haired comic looked fitter than ever as he was pictured taking his luxury car for a spin in London yesterday.
The stand-up star has been on a healthy eating kick since late last year when he was spurred into action to shed a few extra pounds by a computer app.
He showed off his slimline figure during an outing around upmarket Primrose Hill.
Dressed in a baggy black jumper and a pair of blue shorts the comedian looked noticeably trimmer than in recent months.
Michael, 39, was seen hopping into his swish Ferrari which is estimated to be worth around £150,000 for a trip to the corner shop.
He looked relaxed as he enjoyed some down time before embarking on seven dates at London's O2 Arena as part of his Happy and Glorious tour.
Back in May Michael said he was encouraged to embark on a new healthy eating kick.
Talking on Graham Norton's chat show Michael, who admitted he once pulled a muscle getting food out of the fridge, revealed: "I've had lots of clues over the years that perhaps I should lose weight, but something happened in December which finally made me want to do it.
"My son has an app called Akinator the Genie that guesses the famous people you’re thinking of by asking questions, so for egotistical reasons I thought while my son was at school I’d see if I was on it.
"It started asking questions like, 'Is it a man?' and 'Is he American?' and it narrowed it down to a British comedian with dark hair.
"I’m getting a little excited wondering if it’s me in the game and then it asks, ‘Is he slightly over weight?’ so I had a moment of truth, took a deep breath and put in ‘yes’ and it said, ‘is it Michael McIntyre?’ so I haven’t eaten since then!"
