It looks like Fergie got it wrong -- because according to Sia, big girls do cry.

The 'Chandelier' singer couldn't resist posting the audio of her latest tune to YouTube, writing: "SURPRISE! Couldn't wait any longer, here's 'Big Girls Cry'!!" Let's break it down:

'Big Girls Cry' is the third song released from Sia's upcoming album, '1000 Forms of Fear,' and it offers a slower, more melodic beat than 'Chandelier' and 'Eye of the Needle'. Of course, Sia's distinct voice is front-and-center on the serious tune, in which she belts out lyrics like, "I may cry, ruin my makeup / Wash away all of the things you've taken," like she sings on the chorus. "And I don't care if I don't care if I don't look pretty / Big girls cry when their hearts are breaking."

The emotions on the track are one of the singer's strongest points, and we have a feeling that if Sia's 'Big Girls Cry' doesn't actually make you cry, it will definitely have you tearing up.
