Britain's Got Talent fans think they've worked out the identity of Mr Blobby whose act left Simon Cowell absolutely fuming.

The famous character was originally featured on Noel Edmonds' Saturday night show, Noel's House Party, back in the 90s and became a British TV icon. For better or for worse.

Mr Blobby stayed with the show until it ended in 1999, before going on to have a career of his own.

Last night, Cowell, Amanda Holden, Alesha Dixon and Bruno Tonioli were back in action on BGT as the iconic Mr Blobby character took to the stage.

The clumsy pink creature started the act by handing out giant playing cards to the panel.

While the judges seemed to be enjoying his act so far, they had no idea what was to come.

When he accidentally buzzes himself when trying to perform a hat trick, Mr Blobby then picks Cowell to come on stage for a 'special magic trick'.

After some hesitation, the 63-year-old joins Mr Blobby on stage and is put inside a box, as Blobby tries to make him disappear.

But, moments later, Cowell was covered in pink neon slime and the audience were loving it.

While the former X-Factor judge was left absolutely raging, viewers at home were left wondering who the person in the costume might be.

And one celebrity in particular was on everyone's mind.

"Mr Blobby was definitely David Walliams #BGT2023 #BritainsGotTalent," one fan guessed.

While a second added: "Mr Blobby David Walliams in disguise? #bgt #bgt2023 #BritainsGotTalent."

A third agreed: "I bet mr blobby on @BGT is @davidwalliams#BGT #BritainsGotTalent."

"'Now take your Mr Blobby head off and reveal yourself David Walliams' #BGT" a fourth said.

"That’s so @davidwalliams in the Blobby costume. #BGT," another added.

However, sadly Mr Blobby did not progress into the next round and didn't get a single 'yes'.

We thought it was 'gold buzzer' worthy at least.

Last month, Cowell opened up out about the circumstances which saw Walliams exit his role as a judge on BGT.

It was announced late last year that the actor and comedian would be stepping down after a decade on the show, with the show saying at the time that his return was 'up in the air'.

Walliams apologised after leaked audio recordings of him making derogatory comments about Britain's Got Talent contestants were made public.

Speaking to The Sun, Cowell said that Walliams had largely been 'very respectful and emotional' about the talent show contestants, and while it was 'upsetting' to hear what had been said, he was sure it wasn't a constant occurrence.

"I didn’t really get involved in the decision. From what I understand, he decided to take a step back." he said.

"It all happened relatively quickly. I was on holiday and then the next thing is I’m having conversations about who’s going to take his place.

"We did say to the two producers: 'You have to make the final decision' because, yeah, I am an exec producer, but they’re more hands on.

"Obviously everyone had some input - the network, the producers Fremantle, all of us said at the time, these comments are completely unacceptable. I had not heard them before and, yeah, it was upsetting. But from where I’m sitting, this wasn’t something I believe was ­constant."
