The Canadian star was allegedly removed from a plane at the terminal after airport police received a call about an unruly passenger, and he was ordered to wait for another flight later in the day as he was too intoxicated to fly.
Officers were subsequently called back to the scene after Pelletier was reportedly discovered relieving himself by the gate, prompting them to take him into custody for public intoxication.
The 25 year old admits he was escorted off the flight, but claims the media has it all wrong about the rest of the story. He alleges another passenger on the same flight plied him with drinks prior to boarding, and then caused trouble for him once on the aircraft.
He tells TMZ.com, "That (public urination) definitely did not happen... I'm not a big drinker myself to be honest...
"The same guy that (sic) bought me drinks was the guy who got me taken off the plane... that's it. No peeing. Peeing did not happen."
Pelletier is also fighting rumours he landed in trouble with the law for drug possession earlier this month (Dec12), when police are said to have found illegal substances on his person at Gym Bar in West Hollywood.
He pleaded not guilty to two charges related to that incident last week (11Dec12) and is due back before a judge on 17 January (13), but Pelletier is protesting his innocence, saying, "That situation... did not happen."
