The Masked Singer on FOX: Rhino to be unmasked as huge Game of Thrones actor? | TV & Radio | Showbiz & TV

While viewers were initially convinced the character was a sportsperson, some fans now believe it is Gwendoline Christie, who plays Ser Brienne of Tarth in the HBO show.

They wrote: “Gwendoline Christie? Though it would be odd to have two GOT stars on the same season particularly ones who have had screentime together.”

However, the fan added that it would be “odd” to see Gwendoline in the show alongside another Game of Thrones star – namely Maisie Williams, who is said to be under the collar of Kitty.

Gwendoline would be a good guess, as she is particularly tall, and Rhino stands well over host Nick Cannon.
