Martha Stewart has settled on a catchphrase for her forthcoming Apprentice spin-off — but she ain't squealing. "I won't tell you," she teased reporters Wednesday in New York City. "We're saving that for [the] September [premiere]." This much is known: She won't be using Donald Trump's dictum, "You're fired." Apparently, only Melania is allowed to use Donald's dictum. (Oh, no you didn't. Oh, yes I did.)
