The Masked Dancer fans were convinced they had worked out who Frog was after three big clues on tonight's show.
Lots of viewers have struggled to work out who Frog is after several vague clues and songs.
But tonight many people thought they'd cracked it as Frog was the first up to perform.
Frog performed an upbeat dance to Little Shop of Horrors and the judges made several wild guesses as to who could be behind the mask.
Jonathan Ross made the most outrageous guess of them all as he suggested Johnny Vegas.
In the clue package before Frogs performance there were several clues that pointed to their identity.
The year 1984 was a big clue, there was a jack in the box and the word 'Ozzy' was written instead of Australia.
Following these clues many people took to social media saying they were 100% convinced that Frog was Kelly Osbourne.
Tina J Prince said: "Frog is Kelly Osbourne. Ozzy on the map. “Jack” in the box and the show the Osbournes was like Big Brother. Sang little shop of horrors, I’m pretty sure that’s how their family was once described in the good old days. Amazing dancer though."
Michael said: "Ozzy... and the fact that 1984 was mentioned which is the year that she was born, I'm now saying Kelly Osborne for frog."
Sunshine said: "'Ozzy' on the map 'Jack' in the box Ref to George Orwell - she was born in 1984 It's Kelly Osbourne!"
Den said: "The frog is Kelly Osbourne. 100% certainty."
And Maz said: "Frog got to be Kelly Osborne with those clues."
