Ex-England footballer Teddy Sheringham was unveiled as Tree on The Masked Singer last night (Saturday January 18) after a sing-off with Octopus.
Fans of the smash-hit ITV show had been convinced they knew who Octopus was.
But now they've changed their tune, and think that one of two very famous siblings is behind the mask.
However, they were more torn than ever last night as the character sang again and revealed more clues.
Members of the panel even changed their tune when a clue of a picture of a young Jason Donovan was shown.
Immediately, viewers took to Twitter to guess Kylie Minogue.
And even Rita Ora said it was, "definitely Kylie Minogue".
Other clues led viewers to think it was either Kylie, 51, or her sister Dannii.
They pointed out that Dannii had appeared on Comic Relief Apprentice and had a song called Kiss And Makeup.
And yet some viewers were still convinced Kylie was behind the mask.
"This has to be Kylie Minogue," one said.
