The Masked Singer fans have rumbled the identity of Rhino after a big clue tonight.
Rhino has divided fans for the whole of the fourth series - which is fronted by Joel Dommett and sees panellists Jonathan Ross, Davina McCall, Rita Ora and Mo Gilligan all try and work out who is behind the mask. Viewers hadn't been quite sure who it is yet but theories have so far included the likes of James Arthur and Charlie Simpson from Busted.
However, after tonight's clues, it seems like fans have finally worked out who it might be.
In his first clue package, Rhino - dressed in a cowboy style outfit - said "I'm the authority in these parts," as they made their way towards a town called Cobalt, with some fans thinking that hinted towards the band Blue.
They also walked past three arrows before noting they were responsible for '2 Bad Jokes'. Some also saw a link to Love Island when Rhino had said: "I'm chief of this town and happy-go-lucky but one of you guys might think I'm quite muggy."
Giving an extra clue, host Joel Dommett admitted he was a "huge fan" of the person behind the mask.
The following week, Rhino described themselves as "strange and rare" and an "odd one out". There was also shots of the Statue of Liberty as well as an apple, prompting thoughts they could be somehow linked to America, specifically New York.
Rhino was also spotted with an inflatable the following week, much like is used in the iconic TV show due for a revival this year, Gladiators, which led some to think they must be linked to the show.
Saying they can be known to "duel on occasion", there was also a note that said "Danger, Rising Water".
Following tonight's clues including mention of a reunion, fans are now convinced they know who is behind the Rhino costume - and they are desperate to see the band get back together for a new tour.
"More clues pointing towards Charlie Simpson. It’s absolutely him with the reunion clue! #MaskedSingerUK," one wrote, as a second added: "He's talking about the Busted band split and reunion! RHINO IS CHARLIE SIMPSON. #MaskedSingerUK."
A third shared: "Reunion clue for Busted! #MaskedSinger #MaskedSingerUK."
