Ronan Keating was once a heart-throb to millions of teenage girls, but now that he's a father-of-three he wants to appeal to a different audience – and so he's become the singing voice of kids' favourite Postman Pat.
The former Boyzone star will perform all of the vocals - despite his distinctive Dublin accent – in the new movie of telly's most famous postman.
Green Wing actor Stephen Mangan will voice the postie's speaking parts in Postman Pat: The Movie.
Ronan, 36, said: "It's been a true honour to help bring Postman Pat's singing voice to life.
"I grew up watching Pat and all the great characters in Greendale so I can't wait to take my kids along to see them all on the big screen."
Ronan also gets to make a cameo appearance in the film, which sees Pat, who first appeared on BBC1 in 1981, enter a TV talent contest. Pat leaves his home and pals in Greendale as he gets drawn into the limelight.
The film, due for release next May, also stars Jim Broadbent, Rupert Grint and David Tennant.
And as our video shows it looks like the battle of the boy bands continues - Gary Barlow was supposedly to be the voice before Ronan!
