The 46-year-old "Used to Love You" singer rocked a skin-baring ensemble and bold hairstyle that looked like it was inspired by various movies, pop culture moments and YouTube how-to videos -- and she still managed to look gorgeous!

Stefani also wore an Egyptian-esque scarab-like charm around her neck along with a dark green Amazonian-style gown with a plunging neckline, and what appeared to be Native American-inspired accessories and accents.
