Dame Helen Mirren dropped the s-bomb on BBC Breakfast News, while speaking on the subject of John Gielgud.

Mirren used the expletive while describing her admiration, as she paid tribute to the late actor by praising his clipped accent and his penchant for curse words.

“He was always my inspiration for the choices he made, he was this great knight of the British theatre. He always took such edgy choices, and he would always say in that wonderful voice he had,” said Mirren prior to cussing on air.

This is not the first time the actress has been caught swearing live on air.

In 2007, she swore on camera during a red carpet interview at the Baftas.
