Sia Without Makeup

Oh hai, Sia! You supa cute.

It's hard not to love this talented singer-songwriter from Down Under. Not only is she the creative force behind hits like Rihanna's 'Diamonds' and David Guetta's 'Titanium' (on which she also sings), but she also has an amazing solo discography, which you should definitely check out if you haven't already.

Sia is a free spirit and doesn't really wear a lot of makeup, unless it's a bit of lipstick to an event or for performance purposes, in which case she's known to go absolutely H.A.M. with the stuff. Here, she's pictured on Christmas morning, fresh out of bed with zero makeup and a smile for her Tweeps.
