Sia's new music video 'Elastic Heart' features 'naked' Shia LaBeouf

Sia has released her new music video 'Elastic Heart', which features Shia LaBeouf shirtless and wearing nude material.

The video also stars the singer's regular stand-in Maddie Ziegler wearing skin-coloured leotard and matching Sia wig, as the mismatched opponents chase each other around in a choreographed stand-off inside a cage, Stuff.co.nz reported.

Sia had earlier revealed on Twitter that she would appear on the US comedy sketch show, Saturday Night Live, on January 17.
