Redwater stars Jessie Wallace and Shane Richie appear to be split over a hypothetical return to EastEnders, with Wallace piping up: "I'm happy in Ireland!"
The soap stalwarts left Albert Square for the EastEnders spin-off which is set in Ireland and sees their characters Kat and Alfie search for Kat's long-lost son in a small seaside village.
The duo appeared on the BBC's The One Show to promote the new series, where Irish presenter Angela Scanlon asked them if they'd ever come back to EastEnders if the spin-off show was a hit.
Jessie Wallace initially coyly replied "Never say never", while Shane Richie added: "We were talking about this. I hate the thought of never going back to EastEnders. I'd love to see how we can marry the two somehow."
Wallace then seemed to put a dampener on the possibility when she said: "I'm happy in Ireland!"
Redwater, which is a six-part series, is a co-production from the BBC and RTÉ and was filmed in Dunmore East, Co Waterford and Co Wicklow over five months last year.
Richie previously described Redwater as "a standalone story - even without Kat and Alfie in it".
"It's about this Irish family that are living in this fictitious town of Redwater that have this dark secret," he said. "And Kat and Alfie kind of turn up in the middle of their story."
It was written and produced by ex-EastEnders producer Dominic Treadwell-Collins and features some great Irish talent including Downton Abbey's Maria Doyle Kennedy, Lost's Fionnula Flanagan and The Commitments' Angeline Ball.
