The One Show descends into chaos after VERY rude joke about Jason Manford’s manhood

THE One Show descended into chaos after a rude joke about Jason Manford's manhood left Alex Jones and Roman Kemp in stitches.

Comic Manford made an unwittingly cheeky comment, which had the whole studio cracking up.

The One Show hosts Alex Jones and Roman Kemp were joined on the sofas yesterday by comedy legend Manford and iconic singer Michael Ball, and his cheeky humour seemed infectious. 

Jason, 42, discussed his role in this year's Manchester Opera House pantomime before a comment from Alex, 46, had them all crying with laughter.

An embarrassed Alex took a few breaths to calm down while Roman, 30, desperately tried to regain control over the BBC show.

During the interview, a picture of Jason in costume with his fellow cast mates as they posed for the upcoming theatre show Jack and the Beanstalk caused Alex to quiz: "Are you Jack and the Beanstalk?"

Roman then Jokingly interrupted: "You're playing both roles of Jack and the whole beanstalk."

The Welsh presenter corrected herself and said: "Well, not the beanstalk."

Jason decided to cause raucous in the studio and cheekily responded: "Well, it depends what you've heard."

Fellow guest Michael burst into laughter while Roman put his head in his hands and giggled while Jason tried to keep a straight face.

In pure pantomime style, the comedian added: "Oh no he isn't!"

As they all tried to recover from their giggling fits, Jsson revealed more information about the show and claimed he was the 'oldest Jack in town.'

Alex snappily responded: "Nah, you can pull it off!"

Quick as lightning, the comedy star quipped 'careful', which provoked even more  giggles from the hosts before he added: "You could do a panto just by yourself."

Alex, with her face bright red, waved her hands in front of her, unable to speak briefly while the Capital radio host laughed away beside her.

Roman, who announced recently that he is quitting his radio show in a career 'refocus', couldn't find his words as he launched into the next segment, but the comedian wasn't finished with the jokes. 

The son of Martin Kemp pointed at him and said: "Stop it."

Jason cheekily replied: "You're careful what you say now, aren't you."

After they all managed to get a hold of themselves, they concluded and moved on to the next section.

Roman admitted after the debacle he was watching his words.
