Singer-turned-performance artist Sia turned up for a surprise show at Calvin Klein’s after party last night in Milan. And at one point, she even flashed her actual face. Donning her trademark face-obscuring blonde wig, the singer treated the crowd at the Fabrique Milano to hits “Big Girls Cry” and “Chandelier”. This time around – unlike when she appeared on US talk show Ellen – the singer left the corner to Baby, and took her spot at the front of the stage.

The Australian singer decided to opt for anonymity just before the release of her album 1000 Forms Of Fear – choosing to up the visuals in her music videos instead. Seasoned pre-teen dancer and Dazed star Maddie Ziegler has played Sia’s mini me in many of her videos – including “Elastic Heart”, which also featured actor Shia LaBoeuf and landed the artist in some trouble for triggering fans. Either way, between last night and her past performances, Sia’s shown that she can school the masses on performance art, one concealed show at a time – even if some onlookers do still confuse her with Lady Gaga.
