Aussie singer Sia's accidental nip slip

Aussie songstress Sia is usually known for shying away and hiding behind her crazy wigs but she's left little to the imagination in a very racy new social media post.

The singer's make-up artist, Tonya Brewer, took to Instagram account to share a snap of the Chandelier singer wearing nothing but a racy white silk robe and a green face mask on Tuesday.

But what really caught peoples attention was her unintentional nip slip.

The 41-year-old singer was seen wearing a racy white robe with a green face mask holding up two fingers in a peace sign, however her robe was not tied properly and exposed one of her breasts.

Sia was apparently unaware of her wardrobe malfunction as the photo caption read, "She just directed her first film. she had no idea her boob was out. thank you for letting me create magic with you @siamusic.”
