With five performers now revealed and seven more still undetermined, The Masked Singer will next week see Alan Carr joining the panel of celebrity clue-spotters - and TWO eliminations.

Last night saw John Thomson unveiled as the face behind Bush Baby - a name that had been mentioned by the panel (Jonathan Ross, Rita Ora, Davina McCall and Mo Gilligan) but not for this particular character.

Perhaps more surprising is that panel member Mo was astonished to discover a bush baby was a real animal and previously thought he had been watching a gecko with a made-up stage name.

"It's only taken five weeks to get that far", quipped presenter Joel Dommett.

But despite the confusion over that character, fans believe they have rumbled the identity of several of the others.

So much so that bookies have changed the odds.

Betfair have slashed the odds on who is inside the costumes of Blob, Viking, Sausage and Robin.

Lenny Henry, aha's Morten Harket, Sheridan Smith and JLS star Aston Merrygold are the celebs respectively tipped to be in the elaborate disguises.

Betfair spokesperson Sam Rosbottom said: "Masked Singer fans seem more confident than ever of the identity of the wacky Blob, with Lenny Henry's distinctive voice convincing viewers and punters alike - so much so that he is a short 1/2 favourite, the same price as Sheridan Smith is to be Sausage.

"Sleuths are also confident in Morten Harket at 5/6 and Aston Merrygold at 4/7 to be Viking and Robin - but it is Bush Baby, Drago and Badger, the odds-on favourite to win the whole show, who still has everyone foxed."

On Twitter, fans haven't stopped guessing who's in the outfits.

One said: "Will young, you are Badger, I'm telling you, you're Badger I will honestly cryyyyy if I get it wrong."

Another said: "Robin is definitely Aston from JLS, thinking Stacey Solomon for Sausage, Gabrielle for Harlequin, H from Steps as Dragon. Not sure about others but throwing out David Walliams for Blob and Christian from A1 as Viking."

A third said: "I'm convinced the Robin on The Masked Singer is Aston Merrygold. I would bet money on it I'm that confident!"

And a fourth speculated: "So, Harlequin is Gabrielle and Sausage is Joss Stone, most definitely. However, is the Dragon Sue Perkins of the Great British Bake-off? I think the Badger is Ne-Yo, but not sure if he is in the UK right now. "
