Tough year for Scott Weiland.  First he's fired (for the second time) from Stone Temple Pilots.  Then Slash throws cold water on his wish to reform Velvet Revolver saying, "None of us have a clue what he's talking about… We're not buying it."

Now Hennemusic.com reports Weiland challenged an audience member to fight him during his solo concert at Irving Plaza in New York City on Saturday.

On tour with his band, The Wildabouts, the singer confronted a heckling fan, telling the man in the crowd: "So you're f**king pulling that f**king, like, gun sh*t off on me? Then come up and meet me one on one, man.

"You play a tough guy from an audience behind a barricade. I'd love to. Yeah, that guy, trust me."

He continued: "I just don't get it. Guys like you f**king waste your money." Then he added to the security staff: "Actually, let him stay here and just get all f**king riled up. He won't be able to sleep tonight."

Here's the video. (Careful: Salty language ahead)
