Sia appears on The Voice and social media EXPLODES

So it looks like people just weren't buzzing off the wig Sia wore while performing Elastic Heart on The Voice UK last night.

In fact, it seems people were pretty mortified for the Australian star, who no longer wants to show her face in public, and just had to go online to vent their feelings.

Taking to Twitter to express disbelief about the star's disguise, The Voice viewers definitely didn't hold back when critiquing the star's look.

Pondering the reason behind her name, some very clever Twitter users came to some very interesting conclusion following the star's performance.

While others just needed to deal with practicalities and called on someone to help the Chandelier singer before it's too late.

Others were totally on board with the meaning behind the song, but seriously struggled with the meaning behind the wig.

If you didn't catch Sia's performance, then check this out and get on Twitter pronto!
