French film actor Gerard Depardieu was caught short on a Paris to Dublin flight and chose not to bother going to the toilet before relieving himself, says airline CityJet.
"I will only confirm that he, in effect, urinated in the plane," a spokeswoman for the Air France-KLM subsidiary said on Wednesday, confirming a report on Europe 1 radio, which interviewed a passenger who witnessed the incident.
According to the passenger, who was not named, the 62-year-old was visibly inebriated and tried to stand up before take-off, when passengers are asked to wear seatbelts, declaring: "I want to piss, I want to piss."
When a stewardess asked him to sit and wait 15 minutes until the jet took off and reached cruising altitude, he said he could not wait. "And there and then he stood up and did it on the floor," she told the French broadcaster.
"We could see he had been drinking. The stewardess was dumbfounded," she added. "No-one said anything. It all happened with courtesy. Mr Depardieu sat back down and the plane returned to the parking area to be cleaned."
The spokeswoman said the incident had taken place on Tuesday evening on board flight AF5010. She did not say whether the company intended to take further action against the popular French star.
