THE Masked Dancer fans are convinced that Strictly stars Kristina Rihanoff and Ben Cohen are double-act Pillar and Post.
The dancing duo are the show's first ever pair and many think the height difference is a huge giveaway to their identity.
Pillar and Post, who are a red postbox with eyes and a big pile of mail, took to the dance floor for the first time over the weekend to show off their impressive dance moves.
The couple were seen pulling off incredible lifts, as the male celebrity character threw the female character up into the air during their performance to Please Mr Postman by The Marvelettes.
Viewers took to social media this week to speculate that the pair could be professional dancer Kristina and partner Ben.

A third echoed: "If Pillar & Post aren’t Janette & Aljaz, then it could be either Ola & James Jordan or Kristina Rihanoff & Ben Cohen #MaskedDancerUK"
Another simply said: "I think Kristina Rihanoff and Ben Cohen. #TheMaskedDancer"
Someone else added: "I think was Kristina and Ben but I think people are right with David and Frankie."

Former rugby player Ben met Kristina on the BBC dancing show in 2013 when they were paired together.
They have since gone on to have a daughter together, while Ben, 42, is dad to 13-year-old twins Harriette and Isabelle - his children with ex-wife Abby Blayney.
It comes after Masked Dancer fans were certain they had worked out that Pillar and Post are David Seaman and wife Frankie.
One viewer said: "OK I find the masked dancer very hard but pillar and post is 100% David Seaman and his wife!"
