Jason Manford has claimed that Catherine Tyldesley broke the cardinal rule of Strictly Come Dancing – she let slip that she was going on the show.
Contestants have to keep quiet about signing up for the BBC dance competition until the news is officially revealed, and over the years many have admitted they struggled not to let the cat out of the bag.
Comedian and actor Manford said Tyldesley spilled the beans when the pair were working on BBC comedy Scarborough together.
He said the former Corrie star slipped out for a secret phone call which was apparently from Strictly bosses.
He said on Good Morning Britain: "We were filming it when the phone call must have come through for Strictly.
“She said, 'I’m not allowed to talk about it.’ She said, ‘What do you think? Should I do it?'"
Manford said the cast told her: “'Of course you should. We want tickets for Blackpool!”

“She was very subtle about it,” he added.
But he admitted they couldn’t resist having a bit of fun by humming the Strictly theme tune when they were on set.
The star said he thinks Tyldesley will do well when she steps out onto the dancefloor.
“She’s a dark horse,” he said.
Tyldesley is taking part in Strictly alongside Anneka Rice, James Cracknell, Dev Griffin, Alex Scott, Will Bayley, Michelle Visage, Viscountess Emma Weymouth, Karim Zeroual, Saffron Barker, David James, Chris Ramsey, Emma Barton and Mike Bushell.
Jamie Laing was also in the original line-up but has been forced to pull out due to injury.
Judges Bruno Tonioli, Craig Revel Horwood and Shirley Ballas will be back on the panel dishing out their critiques when the show returns on September 7.
They will be joined by newcomer Motsi Mabuse, the sister of Strictly professional Oti, who is replacing Dame Darcey Bussell.
