Not much is known about the project that required the Oscar-nominated star to shave her head, but what is known is that she looks totally badass with the close-cut 'do.

Earlier this month, Hudson and Sia were spotted grabbing lunch together in L.A. Hudson still had her long locks, and the "Chandelier" star -- who never performs, and is rarely seen in public, without a wig that covers her face -- turned out sporting a toned-down all-black outfit, minimal makeup, and no wig at all.
