Nigella Lawson has been stopped from boarding a flight to America just months after she told a court she'd taken cocaine.
The TV chef was due to fly from Heathrow to Los Angeles at the weekend but was turned away by British Airways.
It's not known why she couldn't travel but US authorities have a strict policy about foreigners who've admitted taking drugs.
The incident raises questions about the future of her US TV show, The Taste, on which she is a judge.
