Kristen Bell & Dax Shepard open their home to famous friends for Sia video

Sia recruited real-life couple Kristen Bell and Dax Shepard to host a Christmas Eve party for her new video Santa's Coming For Us.

The actors play a 1960s couple preparing for Christmas Day as Frozen star Bell mimes the words to the tune in the new promo.

They welcome TV favorites Henry Winkler and Susan Lucci and Stranger Things star Caleb McLaughlin into their home, while comedian J.B. Smoove dons the Santa suit and arrives at the bash via the chimney.

The track comes from Sia's new holiday album Everyday Is Christmas.
