All My Children actor Michael Nader was arrested Saturday night for allegedly selling a $20 bag of cocaine to an undercover police officer in a Manhattan nightclub. Shortly after his arrest, the 56-year-old actor — who also played Joan Collins's beau on Dynasty — was taken to the hospital for an undisclosed illness. In 1997, Nader was arrested when he got into a scuffle with police after they pulled him over for alleged drunken driving.
