Mon dieu!

Legendary French film star Gerard Depardieu urinated on the floor of an airplane -- while passengers looked on -- after a skirmish with a flight attendant, according to multiple reports.

The actor, 62, was on a delayed Air France flight from Paris to Dublin on Tuesday when he demanded permission to leave his seat and relieve himself.

A passenger named "Danielle" told French radio station Europe 1 that Depardieu exclaimed "I want to piss, I want to piss" -- but to no avail. A flight attendant informed him that the toilets were locked as the plane ascended to cruising altitude, and that the star would have to wait 15 minutes.

Depardieu (perhaps the most well known French actor) then took matters into his own hands -- unzipping his pants and urinated on the carpet.

"And there and then he stood up and did it on the floor," the passenger claimed. "We could see he had been drinking. The stewardess was dumbfounded."

In response to the report, a rep for Air France-KLM said simply: "I will only confirm that he, in effect, urinated in the plane."
