BBC bosses reportedly decided to axe 'Our Girl' after Jacqueline Jossa failed to agree a deal to become the show's lead.
The 27-year-old actress - who is best known for playing Lauren Branning in 'EastEnders' - was eyed as Michelle Keegan's replacement in the military drama series, but Jacqueline was cautious about making such a big commitment and the decision was taken to end the show.
A source told The Sun newspaper's Bizarre TV column: "Jacqueline was a shoo-in to take over from Michelle in 'Our Girl' but ultimately it would have been tough for her to commit to being away for so long.
"Jacqueline knew it was a massive role for her but after the initial call it all went quiet and nothing more was said.
"With the pandemic and restrictions on filming, they felt it was best to just pull the plug for the moment. It's a shame because everyone thought Jacqueline could have had huge success in the role but the chance never really came off."
'Our Girl' creator Tony Grounds recently confirmed the show won't be returning for a fifth series.
BBC bosses and the show's creative team opted to end the military drama following the departure of Michelle, who played lead character Georgie Lane.
Tony said: "With the finale of series four showing Georgie ready to move on with her life, it feels like the right time for us to do the same."
Despite this, Tony admitted he'd be keen to reunite with Michelle, 33, at some stage in the future.
He explained: "Michelle and I are keen to continue our working relationship and, who knows, maybe we'll catch up with Georgie in the future.
"I wanted to say a big thank you to the fans of the show, it's been a joy to write."
