Los Angeles – We always look forward to Sia’s live performances.
Partly because we’re huge Dance Moms fans and we love watching Maddie Ziegler perform.
But also because you never know who else will join Sia and Maddie on stage.
Sia’s Grammy performance this year delivered more than we could have ever imagined.
Let’s all bow down to the queen that is Kristen Wiig! OMG!
