'Twilight' Actor Bronson Pelletier -- Charged with Public Intoxication

"Twilight" actor Bronson Pelletier -- who played a member of the Wolf Pack in the saga -- has been charged with public intoxication stemming from his alleged airport pee incident last week ... TMZ has learned.

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.

Coincidentally, Pelletier's due in court again on January 17th to answer to meth and cocaine possession charges, stemming from his OTHER arrest this month.
