Britain’s Got Talent gets a new judge this week as David Walliams’ Mum replaces Simon Cowell.
With Simon running late to auditions in London, David's mum Kathleen Walliams’ makes a special appearance.
And Kathleen proved to be quite a match for Simon, as she wasn’t afraid to use her buzzer on a number of acts, giving straight talking, no-nonsense critiques.
In fact it takes several acts before Kathleen decides not to use her buzzer and actually put someone through to the next round.
David Walliams said: "What I was really hoping was that she would use Simon’s Golden Buzzer in his absence but she didn’t.
"She was great actually, she was very quick to press the buzzer, of course that’s the thing people often don’t want to do. She was great with her critique and actually some of the audience thought it was Simon! There was no difference.”
“Kathleen is quite hardcore!" agreed Amanda Holden. "David is quite a wuss about pressing his buzzer, he’s always last and he never says no. He just doesn’t seem to be able to give any criticism that’s bad, he’s sweet really.
"But Kathleen, she pressed hers first once, I was like, ‘Woah!’. She was like, ‘Well no, I just don’t think the audience warmed to you!’. She is basically David in a dress and went down like a house on fire. I can see a future for her.”
And BGT co-host Ant later joked, “She’s like a silent assassin you see, because she’s doing it all with a great big smile on her face so you don’t mind. Simon could learn a thing or two from her!”
