David Walliams took a brutal swipe at his former colleague Simon Cowell as he appeared on stage on Tuesday during Advertising Week Europe 2025.
The comedian, 53, took to the stage to speak at the event alongside his comedy partner Matt Lucas at 180 Strand, London.
And he made sure to include a joke about winning Best TV Judge at the National Television Awards four years in a row - an award which Simon has never received.
Host Melanie Rockcliffe said: 'David Walliams, you were a judge on Britain's Got Talent for a decade and won best judge at the national TV Awards four times.'
In response the comedian and former Britain's Got Talent judge quipped: 'Simon Cowell never won once.
'That's all he does is judging. It was a tiny part of my career. For him, it was the focus and he still couldn't win it.'

'He wasn't happy with you was he?' the host asked.
'No,' said David, before adding: 'It was a fun show to do.'
MailOnline has contacted a representative for Simon for comment.
It comes just after The Mail revealed how David and Simon 'are no longer on speaking terms at all' as the feud between the pair became increasingly bitter.
Those who know the pair say Simon has now gone to every possible length to distance himself from the Little Britain comedian.
David decided to leave Britain's Got Talent after he was forced to apologise for describing an elderly contestant as a 'c***' and making vile sexual remarks about a woman taking part.
The comments, made in January 2020 during auditions at the London Palladium, were picked up on the programme's microphones and revealed in December 2022.
During the audition, an older performer engaged in banter with the judges in which he made a jibe about Walliams. After the audition, the pensioner left, at which point Walliams is said to have called him a 'c***' three times.
Another instance occurred after a female contestant auditioning on the same show had walked off stage.

David remarked: 'She's like the slightly boring girl you meet in the pub that thinks you want to f*** them, but you don't… It's the last thing on your mind, but she's like, 'Yep, I bet you do!' '
At the time, a source told The Sun: 'He hasn't taken the decision lightly, but it just feels like time to move on.
'David has decided to bow out after a ten-year run. He wants to leave on a high after a wonderful time.
'His team have quietly been having conversations over the past few days where it has been made clear that David is readying himself to step down – and then producers will start to think about who might replace him.'
David apologised, but nevertheless sued production company Fremantle for misuse of private information and breaching data laws.
The company apologised and said the matter had been resolved and the comedian is thought to have walked away quietly with around £5million.
In recent times, David revealed on TV how he’s named his dog Eric – the same name as Cowell’s 11-year-old son.
Simon also unfollowed David on social media back in October 2023.
