Celebrity chef Nigella Lawson has been banned from entering the United States since admitting to drug use under oath last year, and she was stopped when trying to board a flight from Heathrow to Los Angeles on Sunday.

It isn’t clear what the future will hold for her in regards to her show The Taste, but reports say she was able to check in and get past security before being told she couldn’t board the plane.

“She didn’t seem to say much, but she did not look happy,” a fellow traveler told Daily Mail. ‘She could not get on the flight so she had to turn around and leave.”

During the trial involving her two ex-assistants, Elisabetta and Francesca Grillo, suing her, she admitted under oath that she has used cocaine and smoked marijuana in front of her children.

She will be able to fly to the Untied States in the future, though. All she needs to do is apply ahead of time and she will be granted a visa to travel.

“There are several ways of legally travelling into the United States and Ms Lawson has been invited to come to the embassy and apply for a visa for travel to the US,” a spokesperson for the U.S. embassy said, The Guardian reports. “We understand she has professional requirements for US travel and these matters are generally handled routinely and expeditiously, so stand by.”
