Niall Horan and Lewis Capaldi's antics will be documented in a film by Guinness

Guinness Ireland's documentary about Niall Horan and Lewis Capaldi's recent road trip around Ireland will air this Sunday on Virgin Media One.

The film, entitled Niall Horan’s Homecoming: The Road to Mullingar with Lewis Capaldi, was reportedly inspired by Horan’s desire to "revisit and reconnect with all that he loves of home; to retrace the origins of the exciting life journey he’s on and to experience the reality of Ireland today".
