And so does his alleged mistress Brittney Jones!
"She's a total party animal. She drinks every night, and openly talks about being an alcoholic," claims a source. "I only saw her smoke pot and stuff like that… but I'd almost guarantee you she's done everything in the book."
But she's not keeping her drug use to herself - Brittney likes to spread the wealth with Ashton Kutcher!
The homewrecker sent a text offering to get her movie star friend some herbal entertainment.
"Yeah! Whenever you want I always have weed to share :)" Brittney texted.
But Kutcher must have been pretty desperate considering her behavior the night they met at Lucky Strike bowling alley in Hollywood.
The source continued:
"She was such a train wreck that we all didn't even want to hook up with her. She was constantly talking about how she's been an alcoholic for years and drinks every day; drinks a bottle of wine a day and all this other stuff."
