The Masked Singer's latest episode aired tonight (February 3) and viewers are convinced they know which celebrity is hiding behind the Bigfoot mask.

The ITV show sees celebrities perform in a variety of costumes and the celebrity judges and viewers at home try to guess who is behind the mask before they are revealed.

While guesses are varied, some viewers think the celebrity behind the mask is comedian and presenter Alex Brooker.

The Bigfoot costume is thought to be a link to Brooker being an amputee - he had his leg amputated when he was a baby and now wears a prosthetic leg.

Bigfoot sports a bandaged foot and is always seen holding one crutch.

ITV viewers guess Bigfoot is Alex Brooker

With this in mind and the other clues picked up during the series, some fans believe it's Brooker behind the mask. 

Each week, viewers take to social media platform X, formerly known as Twitter, to pitch their guesses.
