London, July 10 : Britney Spears' was busted recently, when an auto-tune-free version of her song ' Alien' was leaked online

Producer William Orbit confirmed the leak on his Facebook page and revealed that the 32-year-old artist was just "warming up" in the clip and it was not supposed to be shared with millions of listeners, the Daily Star reported.

The British composer also defended the 'Baby, One More Time' star stating that he's "heard all manner of sounds emitted during warm-ups" and whoever leaked the clip must have done so in a spirit of unkindness, however, it could in no way detract from the fact that Britney is magnificent. (ANI)
