Meanwhile, in September, Ramsay spoke to PEOPLE about fatherhood and how his children have “brought the most emotion” out of him.

“It’s funny, isn’t it? Because everyone thinks, ‘God, you must be an absolute ass to be at home with.’ [But] Tana’s super fierce, an ex-Montessori school teacher. So I’m the softie,” he told PEOPLE.
