Ronan Keating has joined the voice cast of the upcoming Postman Pat film.

The Boyzone singer has lent his vocals to Postman Pat: The Movie for scenes where the main character is singing.

The Irishman commented: "It’s been a true honor 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."

Keating will also feature in the movie as a contestant who competes against the postman for a special prize.

The animated film stars Stephen Mangan in the lead role, whilst David Tennant and Rupert Grint also feature.

It will be released on May 23.
