The Scots presenter welcomed EastEnders’ actor James Bye, who plays Martin Fowler this morning on her show as he spoke about what was next for his character ahead of the BBC soap’s return next Monday.
However, with the excitement of Strictly Come Dancing bubbling, Lorraine asked Maisie’s co-star about the actress supposedly joining the show.
Earlier on in the programme, Lorraine had announced Prince Harry’s pal JJ Chalmers had become the eighth to join the line-up.
Lorraine added James’ co-star Maisie had also signed-up and asked what he thought of the Tiffany Butcher actress’ new move.
He appeared to back up the revelation from the host, responding: “Good luck to Maisie, of course, she’s going to do to Strictly!”
However, Lorraine backtracked moments later, saying it was just a rumour.
This caused a slightly awkward moment between the pair and James noted his co-star would be great if she were to join the show.
Those tuning into Lorraine rushed to Twitter to comment on Lorraine’s slip-up.
One posted: “Maisie wasn’t confirmed…until now #Lorraine! #Strictly.”
Another added: “Well done James for practically confirming that Maisie Smith is joining #Strictly #lorraine.”
It comes after the host had revealed JJ Chalmers would be in this year’s line-up just a few minutes earlier.
JJ is a former Royal Marine and Invictus Games medallist, who lost two fingers whilst fighting out in Afghanistan.
The latest hopeful opened up to the ITV host on his friendship with the Royal Family member, who he met around five years ago.
Speaking on whether his friend would be watching, he said: “I think he’s going to be following. I think he’s going to have a great laugh.
“The idea is that this is a culmination of 10 years of my recovery and he’s been a big part of that. He should have massive pride one of his lads has gone on to do this.
“He gave us the passion and the belief in ourselves so I’m going to give this my all.”
Earlier this morning, comedian Bill Bailey had been announced to be part of this year’s billing.
But on This Morning, Holly and Phil revealed that the rumour was in fact true and that Maisie would be joining the line up.
She joined them via video link to chat about the news.
