David Walliams stripped off AGAIN on Britain's Got Talent 2017 tonight, baring his bum to reveal a 'tattoo' of his co-judge Simon Cowell!

Saturday's episode saw David drop his trousers during hopeful Sue Moretta's audition, much to Simon's chagrin.

And tonight the former Little Britain funnyman flashed his flesh again as part of a game on ITV2 spin-off show Britain's Got More Talent.

Recalling a moment earlier in the series when he met a man who has Ant and Dec tattooed on his bum, host Stephen Mulhern explained that one of the judges had got an inking of Simon.

His challenge was to pose each panellist a question each to determine who the culprit was.

David was asked which part of his body he'd decorated, but responded: "I don't have a tattoo."

Alesha Dixon claimed the process took "about four hours" to complete - while Amanda Holden insisted it didn't hurt, teasing: "I've got a massive pain threshold."

Despite David's claim, Simon correctly guessed he had the tattoo.

The comedian promptly got his bum out, revealing a graphic of their faces captioned: 'Forever in love'.

Simon was horrified by the display, reacting: "You know what, I'm not paid enough money to deal with that!

"I feel sick! I didn't like it!"

Thankfully for him, we're guessing that David's inking probably isn't real.

The judges are likely looking for other ways to amuse themselves after BGT bosses removed their power to help decide the finalists.

This year, only viewers' votes will decide which contestants goes through to the grand finale.

Amanda joked that the change means the foursome are now more like a "posh Gogglebox".

The Britain's Got Talent semi-finals air nightly until Friday at 7.30pm on ITV, with More Talent on ITV2 straight after the results.
