Britney Spears' unedited Alien song was leaked online and people are hating on it. There were rumors that Alien was going to be a collaboration with Lady Gaga. The producer was quick to point out on Facebook that this was an early demo of Alien and not the version that would be appearing on Britney's new album.

Britney's demo was recorded clean and the version that was leaked had no autotune and none of the post-production tricks that make a song album-track-worthy.

Britney Spears' "Alien" was the opening track to her album, "Britney Jean." The song was written by legendary producer William Orbit, who worked studio magic on Spears' vocals before the album was released.

Spears has been teasing about the Alien song for weeks. She called the song "really cool" and "really great."

Orbit took to Facebook to explain the recording process. His full letter follows:

"Dearest Music Lovers, I have heard that Britney vocal link that everybody's been discussing. It has been impossible not to as there have been many comments directing my attention to it. [I won't re-posting it here]. 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 vocalisations in order to get warmed up.

"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 warmups.

"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.

"Whomever put this on the internet must have done so in a spirit of unkindness, but it can in no way detract from the fact that Britney is and always will be beyond Stellar!

"She is magnificent! And that's that."
