Can anyone tell me where this sample comes from?

Ehhh I know this is pretty much a hopeless shot in the dark, but who knows, fluther has pleasantly surprised me in the past. In this song the females vocals sound insanely familiar to me. Its driving me mad cause I cant place wtf song ive heard it in before. Part of me thinks its from a Shpongle song, but im failing to find any that have it.

Anyone have any idea where in the hell its from?
