Nigella Lawson says having her private life raked over in a London courtroom was "mortifying" but she is putting the case behind her.

The celebrity cook testified last month at the fraud trial of two former aides, who were ultimately acquitted of funding a luxury lifestyle with credit cards loaned by Lawson and her ex-husband Charles Saatchi.

The trial was overshadowed by allegations about the domestic life of Lawson and Saatchi, including claims that Lawson regularly used cocaine.

She denies regular drug use.

Lawson told "Good Morning America" on Thursday "to have not only your private life but distortions of your private life put on display is mortifying."

But, she added, "since then I've eaten a lot of chocolate, had a very good Christmas and am into the New Year."
