EXCLUSIVE
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 spins around, whips out his penis and starts peeing ... for a very, very LOOONG TIME! Interestingly, the airport employee stands by patiently waiting for him to finish.
TMZ broke the story .. Pelletier was arrested 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 has 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.
