Singer Sia has been around for a long time, so long in fact that many of us can't recall what she looks like without her now perma-wig - albeit in different forms...

So many thanks to Missy Elliott who posted the below to her twitter a few hours ago, showing Sia in all her lovely full-faced glory. We're not sure where the wig was, but it was probably chilling on the couch for the evening, taking a well-earned rest.

In case you missed her Carpool Karaoke, it's almost as good as Adele's... Almost.
