Tab Flab: Apparently, John Cusack is in danger of becoming too big of a star. Why else would producers of his upcoming flick The Contract send him a personal trainer to prepare for the shoot. But according to the National Enquirer, the suits were befuddled when Cusack reported to the set looking just as flabby as he'd been before. Turns out Cusack, who doesn't like to work out, sent a buddy-double to the trainer to crunch and flex and tone. Who knows, maybe his pal's pecs will get a cameo in the film? But if producers really wanted John to slim down, they should have written it into, hello, The Contract.
