Harriet Rose, who presents the spin-off show, shared a bombshell about the upcoming final

The host of The Masked Singer spin-off show has revealed she knows the identity of one of the finalists after accidentally bumping into the star.

Harriet Rose, who hosts the spin-off show The Masked Singer: After Mask, and host of the main ITV show Joel Dommett were guests on Loose Women on Thursday, February 13.

The duo joined panelists Charlene White, Sunetra Sarker, Gloria Hunniford, and Nadia Sawalha to discuss the upcoming final featuring Pufferfish, Dressed Crab and Wolf as they prepare to compete for the 2025.

Amidst predictions and backstage gossip, Joel and Harriet confessed they had no insider information about the identities behind the masks – except one.

However, Sunetra was sceptical about the hosts’ claim of ignorance about the celebrities on the show.

“Do you not know? ” she questioned, to which both hosts simultaneously responded: “No.”

Harriet then interjected, stating: “I’m telling you now, that set is locked down,” before revealing: “I got more access, not boasting, but I got more access than Joel.”, reports the Mirror.

Harriet then shared an incident where she accidentally encountered a contestant backstage, violating show protocol.

Typically stringent measures are put in place to conceal the identities of celebrities on the show from nearly everyone, limiting the number of people aware of the cast.

This is to lower the chance of information being leaked before broadcast.

Discussing a backstage blunder, Harriet inadvertently disclosed that she encountered one of this year’s finalists and implied she had learnt their identity.

The presenter revealed: “I got to go backstage where they all hangout and we actually bumped into one of the Masked Singers. Who is yet to be revealed.”

The Masked Singer final airs at 7pm on ITV1 on Saturday, February 15.
