Beware of flying copper pots: CBS is talking to Cybill Shepherd about reprising her role as Martha Stewart in a May sweeps biopic. Shepherd first played the domestic diva in NBC's camp classic, Martha, Inc. According to Variety, CBS' Martha movie will have a more serious tone than NBC's pic, so it's doubtful we'll hear Shepherd do an encore of Stewart's famous, "Hey, slut! I'm writing your parents a letter telling them you're a whore!" line. Damn.
