The identity of Blob was finally revealed in the sixth episode of The Masked Singer.
Although many viewers had it worked out from the start, some were amazed by the unmasking on the secretive ITV singing show which has a judging panel and fans at home guessing which celebs are behind the wacky costumes.
Step forward Sir Lenny Henry, who had fun incognito as people thought Blob could have been fellow comedians Romesh Ranganathan and Greg Davies.
One fan tweeted: "That was a surprise to see Blob was Lenny Henry.
"I had it in my head it was Greg Davies."
Another tweeted to him: "I never thought that Blob was you.
"I had it in my head it was Greg Davis because of the comic stand up the acting and the teaching reference too."
"Lenny Henry! Who saw that coming!?"exclaimed another.
Judge Davina McCall guessed that it was Sir Lenny, 62, just before he was unmasked.
Other fans took to Twitter to boast they'd always known it was the stand-up comic and actor from Dudley.
"I can’t believe I guessed #blob from the first show," said one.
"I KNEW IT! Knew from episode 1 who it was," shouted another.
"Lol. Easiest guess ever," said another.
Sir Lenny said it was 'really intense security behind the scenes.'
"I wore a sweatshirt that said 'don’t speak to me' and I had to wear a visor and gloves," he explained.
"I looked like a mute alien.
"People were very kind though.
"When I was behind the scenes people would smile and give me the thumbs up. It was a weird but positive experience."
The Masked Singer is screened on ITV on Saturdays at 7pm.
