Fans who visit the Westlife website can play a part in the new video simply by submitting their name.
The name is then digitally integrated into a number of scenes, featuring on a wedding invitation and in a text message sent by a member of the band.
The interactive video for their twentieth single 'The Rose' has been created by British firm 20:20 London.
The company has used the technology in online adverts and computer games before, but this is the first time it has featured in a music video.
