VIDEO: Michael Bublé's Christmas message for families in cute new Down's Syndrome karaoke video

CHART-TOPPING crooner Michael Bublé has given a helping hand to a festive musical video by campaigning parents and their kids.

The Canadian singer gave the all-clear for families involved in the #WouldntChangeaThing drive to challenge perceptions of Down’s Syndrome to lip-synch over his cover of All I Want for Christmas is you.

The video stars members of 25 families signing and signing, including Manvers mum Rachel Blencowe and daughter Amelia, and has so far clocked up more than 23,000 YouTube views.

It was premiered on ITV show This Morning, with Bublé popping up with his own video message to introduce the clip.

The prolific families have collaborated on three videos this year — including a Carpool Kareoke version of Christina Perri’s A Thousand Years and a tribute to The Greatest Showman’s Tightrope.

Campaign group Wouldn’t Change a Thing aims to challenge negative perceptions of people with Down’s Syndrome.
