This is supposedly Britney Spears' song "Alien" without auto-tune or editing.

Music producer William Orbit came to her defense on his FB:

"Dearest Music Lovers, I have heard that Britney vocal link that everybody's been discussing," he wrote. "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 vocalizations 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."

* Do you think it's really her? If so, is she merely warming up?
