One Direction star Niall Horan has been transformed into an old man for their new video.

The lads are releasing the track 'Best Song Ever' as their next single and its promo clip will be unleashed on Monday (July 22) alongside the tune.

The team behind the group are teasing the video every day until its release and today (July 16) pictures were released of Niall Horan's character in the clip.

The Irishman can be seen with prosthetic makeup on his face and thinning hair on his head as he plays the part of an old man.

More characters from the video meanwhile are due to be unveiled this week.
