It looks like Janice Dickinson is in the running to become America's next out-of-work former supermodel. UPN announced Thursday that Dickinson is being replaced on America's Next Top Model by '60s runway icon Twiggy. A network rep says Dickinson is "leaving to pursue other projects" including VH1's Surreal Life" as well as a TV production deal and a new book. Our sources, however, say the ol' bat was angling for a pay raise and didn't get along with host Tyra Banks. Who are you gonna believe?
