Bronson Pelletier may have trouble talking his way out of this one.

The Twilight Saga actor was arrested in December on charges of public drunkenness, with police claiming Pelletier had to be removed from a flight... only to then relieve himself while detained near a gate at LAX.

And, based on the video posted here (courtesy of TMZ), that's exactly what happened!

Bronson had initially denied the urinating allegation, but his rep now admits: Pelletier has a substance abuse problem and will be entering rehab in the near future.

We hope he receives the help he needs, no matter how many times we watch and laugh at the clip above.
