Is Paul Giamatti Playing Ken Jeong's Crimeboss In The Hangover 2?

Speaking with Metro News, Paul Giamatti let slip a few details about his character in The Hangover 2, saying that he's a "bad guy," connected somehow with Ken Jeong's Mr. Chow character. I was wondering how they were going to fit in Mr. Chow, the funniest part of the first movie, and making him an underling to an evil Paul Giamatti would certainly work for me. Just so long as it turns out they're part of a web of intrigue controlled by President Bill Clinton, of course. [Metro]
