'You don't want to mess with these guns!' Piers Morgan hilariously takes on bodybuilder James 'Flex' Lewis in arm-wrestling competition

He's not shy when it comes to taking on tough interviewees.

And the tables were turned on Piers Morgan when he challenged a professional bodybuilder and Mr Olympia champion James 'Flex' Lewis to an arm-wrestling competition live on Tuesday's Good Morning Britain.

The co-host, 52, who boasted that he could beat one of his two brothers in arm-wrestling, due to his 'big guns and good wrist action', challenged James, 34, to a duel live on-air.

 After a pleasant interview with the Welshman, a typically bolshy Piers said: 'You've got a big reputation, you got big arms, this time of year, I always take on my two brothers at arm wrestling

'I have a particularly good technique, big guns up here and a good wrist action so I just think maybe we should get it on' to which Flex replied 'Lets get it on!'.

  As an enthusiastic Piers did some arm stretches, an impressed Flex felt his upper arms and said 'mate  you have got big arms to which Piers responded 'Mate you don't want to mess with these guns. I'm serious'.  

As the pair duelled, it looked as if they were on level pegging with Susanna shouting out: 'Come on Flex, don't let him win.'

Speaking of the Terminator star who presented him with the award he said: 'He does this thing where he tries to one-up you, I knew so I had something ready so I could one-up him.    

'I've done quite a lot of stuff in the US, he's the blueprint, he thought I'm going to make it in movies and nobody thought he would and he proved them all wrong.'
