Iain Lee has appeared to let slip the first three Strictly Come Dancing contestants for this year's series.
However, Iain said the three stars are "supposed to be" Sam Allardyce, Jamie Laing and Anneka Rice - leaving hosts Ben Shephard and Kate Garraway stunned.
He said: "They are going to announce the first three contestants tonight on The One Show.
"It's supposed to be Sam Allardyce, Anneka Rice and Jamie Laing."
Ben cut in: "Hang on, they're supposed to be announcing later and you've already announced it."
Pretending to be shocked, Iain said: "Sorry One Show!" as the hosts laughed.
Ben then teased that Sam could be doing the show, saying: "I do know Sam quite well."
Ent Daily has contacted a rep for Strictly for comment.
Hang on, they're supposed to be announcing later and you've already announced it.
Meanwhile in Strictly land, the show announced a new professional dancer yesterday.
World-class Latin dancer Nancy Xu will be joining the group of professionals this year as rehearsals get underway for the new series of the dance competition.
Nancy, 28, said: "I'm thrilled and excited! I cannot wait to start this new journey with all these amazing people and share the magic together."
Strictly has now revealed the final line-up of professional dancers for this year's series.
The male pros taking part are: AJ Pritchard, Aljaž Škorjanec, Anton du Beke, Giovanni Pernice, Gorka Marquez, Graziano Di Prima, Johannes Radebe, Kevin Clifton and Neil Jones.
The female dancers will be: Amy Dowden, Dianne Buswell, Janette Manrara, Karen Hauer, Katya Jones, Nadiya Bychkova, Luba Mushtuk and Oti Mabuse.
Meanwhile, the show is also introducing a brand new judge to replace Darcey Bussell - who quit the show in April after seven series.
Last week, the BBC has revealed Oti's sister Motsi, who is a judge on Strictly's German version, will take Darcey's spot on the panel.
Former South African Champion and German Latin Champion Motsi said in a statement: "I am absolutely overjoyed to be joining the Strictly judging panel.
Meet our incredible new Judge Motsi Mabuse! She’ll join Craig, Bruno and Shirley when #Strictly returns in the Autumn. Find out more about @MOTSI_MABUSE here 👉 https://t.co/f0dSMHc4E8 pic.twitter.com/0fme69vwKT

"I have so much respect and admiration for the other three judges and hope to add my own bit of sparkle to the show. I can’t wait to get started!"
Strictly's Executive Producer Sarah James added: "I am incredibly excited that Motsi Mabuse is joining the show.
"Motsi's natural warmth, energy and passion for dance makes her the perfect addition to our esteemed judging panel."
