Louis Walsh fronts toy brand Elves Behavin' Badly's 2018 Christmas campaign, playing an elf help ambassador, encouraging families to buy a naughty elf toy this year.

The former X Factor judge tells the story of two troubled elves 'who've been kicked out of their homes for joyriding reindeer and getting up to no good', and asks the public to share pictures of their elves on social media, commenting 'Last year Elves Behavin’ Badly caused a viral sensation but this year they’re set to top the Christmas toy charts... I can’t wait to see what people get up to with their elves in the run up to Christmas'.
