Celebrity chef and author Nigella Lawson and her husband, global advertising executive and art collector Charles Saatchi, are officially divorced.
And it happened in record time – at a 70-second hearing Wednesday, according to the U.K.'s The Guardian
The official end of their marriage comes just seven weeks after shocking photos
of Saatchi with his hands around Lawson's neck as they apparently argued inside a London restaurant.
Saatchi, 70, eventually accepted a formal citation
, admitting that he assaulted his wife, after a police investigation.
He later released a statement
announcing plans to divorce and saying he was "disappointed" in his wife, 53, for not publicly supporting him and letting people know he had never physically abused her.
The couple had been married for 10 years.
