WATCH: Miley Cyrus Comes Under Fire From Viewers For Live Vocals On 'The X Factor' (VIDEO)

Miley Cyrus might have stayed covered up for once for her appearance on Sunday night's 'X Factor' but she still came under fire from viewers - this time for her live vocals.

After performing her power ballad 'Wrecking Ball' atop a sand dune (as you do) viewers quickly took to Twitter to call out her live vocals - with one saying she sounded like 'a goat'.

WATCH: Sam Callahan and Luke Friend battle it out in the sing-off. Who went home?

Twitter user Tom, tweeted: "Is Miley Cyrus ok? At least we can be 1000% sure she isn’t miming, good on her for giving it a go."

Sophie added: "No one should ever let Miley Cyrus sing live again."

"Miley Cyrus literally sounds like a goat," agreed Caroline.
