Owen Wilson is so concerned people will think he's doing drugs in bathroom stalls that he's taken to leaving them open when he goes in to do his business.
A spy for Page 6 made note of this revealing new strategy of Owen's at a recent L.A. Museum of Contemporary Art event, saying:
He was with a girl with blond highlights, and he went to the bathroom and peed with the door open.
Wow, she had blond highlights? Oh - and he peed with the door open. So people would see he wasn't doing drugs. Good idea.
He's totally doing drugs.
