Pharrell Williams has brandedMiley Cyrus "a threat", exclusively telling N.E.R.D. star - who has worked with Cyrus on the LP - at theBecca Dudley: "The world has no idea who she really is, they've gotten just a slice.

"If you think about it, when you were 20-year's old and you threw caution to the wind, you did so. Your friends were around, your family was around, strangers were around but it was in the confines of your own privacy, she's done so in public."

Williams continued: "It's interesting because while everyone thinks they know who she is and what she's all about now, and they're like, 'Oh, we got it. We saw that performance, we know.' You have no idea.
