Bronson Pelletier can't deny it anymore -- the 'Twilight' actor definitely took a leak right in the middle of LAX last month ... and there's video to prove it.
In the video, an airport employee approaches Pelletier ... and then he stumbles around, whips out his penis and starts peeing ... for a very LOOONG TIME!
Interestingly, the airport employee stands by patiently waiting for Pelletier to finish ... until police show up to arrest him.
TMZ broke the story ... Pelletier was busted for public intoxication at LAX after getting thrown off a flight for being too drunk.
Witnesses said Pelletier urinated at the gate moments after he was removed from the plane, but the actor had insisted he did no such thing.
A rep for Pelletier tells TMZ ... Bronson realizes he has issues, and will be entering a treatment program for addiction in the near future.
A rep for the L.A. City Attorney's office tells us, Pelletier was charged with one count of being drunk in public, a misdemeanor, after he allegedly urinated in the middle of an LAX terminal while waiting for a flight last Monday.
If convicted, Pelletier faces a maximum of 6 months in jail. He's due back in court for his arraignment on January 7th.
Pelletier has DENIED the public urination part of this case ... but that's still in question, based on this video of the arrest.
