Joan Rivers unleashed an earful of insults after Donald Trump fired her daughter on "The Celebrity Apprentice."
Rivers' targets: poker champ Annie Duke and Playboy pinup Brande Roderick.
Melissa Rivers, who appeared with her mom on the NBC show, claimed the two formed an alliance against her. She called them "pit vipers."
Joan Rivers launched into mama-bear mode, calling Roderick a "stupid blonde" and Duke a "white trash" poker player. She called the duo "a Nazi and a follower."
NBC representative Amanda Ruisi didn't immediately return phone and e-mail messages seeking comment. Donald Trump could not immediately be reached.
