Supermodel Naomi Campbell has been forced to pull out of pal SEAN COMB's reality TV cook-off, CELEBRITY COOKING SHOWDOWN, after being charged with beating her assistant. The British stunner told the rap mogul she'd be unavailable for his upcoming show after hearing her maid ANA SCOLAVINO planned to charge her with assault last week (ends31MAR06) after she allegedly hit her with a jewel-encrusted cell phone. Diddy confirms, "Naomi's not in it. She's been out for like two weeks." And show host Alan Thicke jokes, "Naomi was booked and then got booked again, apparently at some precinct in New York." Campbell was set to show off her culinary skills opposite soul diva Patti Labelle in the inaugural show, which airs in the US on 17 April (06).
