Oops! Britney Spears singing ‘Alien’ without Auto-Tune leaked online

UPDATE: The unedited version of “Alien” has since been removed from YouTube. We’re not surprised.

Yes, you’ve heard what Britney Spears and other singers sound like without the advantage of Auto-Tune. But holy cow, we’ve never heard Spears sound like this.

Last week someone leaked an unedited vocal track of the song, “Alien,” from her most recent album, “Britney Jean.”

And it’s so cringe-worthy that her producers felt compelled to release an explanation to Facebook on Monday.

They want us to know that the make-your-ears-bleed version was never meant to be heard.

Ya think?

Spears was just warming up, wrote track producer William Orbit.

“I’d like to affirm that ANY singer when first at the mic at the start of a long session can make a multitude of vocalizations in order to get warmed up,” he wrote.

“Warming up is essential if you’re a pro, as it is with a runner doing stretches, and it takes a while to do properly. I’ve heard all manner of sounds emitted during warm-ups. The point is that it is not supposed to be shared with millions of listeners.

“A generous singer will put something down the mic to help the engineer get their systems warmed up and at the right level, maybe whilst having a cup of herb tea and checking through lyrics before the session really kicks off. It’s not expected to be a ‘take’. I think that 99% of you reading this will totally understand.”

Whoever leaked the track “must have done so in a spirit of unkindness,” he said.

Here’s Britney’s naked singing voice.

Now give a listen to the song’s final version.
