He's the city's best-known nightclub doorman and a sometimes actor who once battered a man with the "business-end of a velvet rope."
Now that you have an idea of who we're dealing with, here's the latest news from Wass: He recently revealed to Page Six that he threw away a bunch of drawings given to him by the artist Jean-Michel Basquiat.
"Every time I would see him, he would draw me a little picture on a napkin or a VIP ticket, which I, of course, threw away, thinking it wouldn't be of any worth," said Stevens.
Apparently, back when Stevens was working the door at Palladium - a haunt of artists like Andy Warhol and Keith Haring - he'd blocked Basquiat from entering the VIP room.
"I told him he was a crackhead and to get the hell away from me," he recalled. But, at the behest of Warhol, he changed his mind and let Basquiat through. Stevens assumes the drawings were a kind of thank-you.
Though we don't know exactly what these type of casual napkin drawings would be worth today, seven lots of Basquiat's drawings on paper recently sold for prices ranging from $25,000 to $125,000.
Talk about an expensive mistake.
