Michael Barrymore was asked to leave a restaurant after launching a foul-mouthed verbal attack during the filming of Celebrity Coach Trip.
According to The Mirror, the former Strike It Rich host squared up to a French waiter before calling him a "c***".
"He was necking wine and becoming louder and louder. When a waiter looked at him, Michael lost it and started shouting and swearing, calling the poor chap a 'c***'," a source claimed.
"Glasses got smashed. Michael tried to goad him into throwing a punch. It was horrible. Michael is incredibly unpopular."
Barrymore also reportedly argued with other contestants including Alex Best, Lembit Opik and Lizzie Cundy.
His spokesman confirmed the allegations, but insisted that his behaviour was a side effect of the medication he has been prescribed since falling off a horse last week.
He said: "He has been unsteady and disorientated. A customer took exception as he moved around the tables, they had an altercation."
