THE Masked Singer viewers are convinced a top boyband singer is behind the Bigfoot mask.
Fans of the ITV series previously insisted the furry brown and purple spotted creature was hiding the identity of a huge Strictly Come Dancing star.
Now they reckon Blue's Anthony Costa, 42, is a name in the frame.
Aged just 20, he burst onto the pop scene as part of the four-piece band, with the group clocking up three multi-platinum selling albums between 2001 and 2005.
It came after The Masked Singer uploaded a video of the cute character boogying around with its bandaged left foot to its Instagram page.
The caption read: "STOMP your feet and give #BIGFOOT a BIG round of applause!"

One fan promptly replied: "Antony Costa."
They called out the All Rise hitmaker ahead of tonight's episode.
Teaming up with Lee Ryan, Simon Webbe and Duncan James, Antony released hit tracks such as Too Close, Guilty, One Love, and the Elton John collaboration, Sorry Seems To Be The Hardest Word.
He also wowed fans with his solo work - meaning he has more than enough confidence to perform on The Masked Singer stage.

The character - who arrives on-stage armed with a crutch - previously performed Moana track You're Welcome, which was originally sung by Dwayne 'The Rock' Johnson.
It has also belted out Frank Sinatra track Come Fly With Me - the perfect track for a seasoned singer like Antony.
The furball has offered a variety of complex clues as to its identity through the series.
During one episode it teased: "You may think my talent is quite preposterous, but my strength was once linked to a sporting rhinoceros."
It has also told viewers to "act your age not your shoe size" as well as admitting they have a "cast of Friends."
Bigfoot has also made mention of everything from Amazon packages to Hogwarts.
Additionally, earlier in the series, others have suggested Bigfoot is TV favourite Alex Brooker.
They insist the character's name is a reference to his TV show The Last Leg - and the fact he wears a prosthetic leg.
