JUDI Dench ordered Louis Theroux out of her house after a savage age swipe against the star.
The award-winning actress and Dame featured in one of Louis' documentaries for the BBC.
While the pair were sitting down discussing memories from Judi's past, Theroux landed himself in trouble.
As she discussed her childhood, the 88-year-old said: "I've had a lot of pets, we had 17 cats during the war."
Louis then replied: "During which war?"

The James Bond actress was left less than impressed as she told him: "Well the Second World War, Louis."
As he tried to save himself by clarifying that he didn't mean the First World War Judi interrupted him and said: "Out!"
After the tense moment Louis, 52, told her "I thought you might mean the Vietnam War".
Judi then calmly responded by reassuring him she meant the Second World War.
In an attempt to breathe a sigh of relief he then asked Judi "Did I recover?" before the pair broke out in laughter at the exchange.
Judi, who has macular degeneration, said she finds its "impossible" to read scripts nowadays.
The condition causes a gradual loss of vision but it does not cause total blindness.
However, it can make everyday activities such as reading and recognising faces difficult.
Speaking previously about her diagnosis, she said: “It’s become impossible and because I have a photographic memory, I need to find a machine that not only teaches me my lines but also tells me where they appear on the page.
“I used to find it very easy to learn lines and remember them. I could do the whole of Twelfth Night right now.”
