The 46-year-old singer attended pal Shelli Azoff's star-studded birthday party on Friday in Los Angeles, and definitely turned heads in an edgy black dress featuring panels held together by black vertical ribbons. Stefani paired the unconventional frock with fishnet tights and black-and-gold stiletto Azzedine Alaïa boots.
Although, Stefani probably showed a bit more than she bargained for from the back, exposing her butt as she walked.
Guests at Azoff's party included Kim Kardashian West, Kris Jenner, Kendall Jenner and Nicole Scherzinger. Azoff is the wife of music executive Irving Azoff, who represents Stefani's band No Doubt, Maroon 5, Christina Aguilera, and Journey, among other A-list clientele.
Stefani has been noticebly bold when it comes to her fashion as of late, and last Thursday, she confidently wore one of her sexiest looks ever while performing at Samsung's 837 Summer Concert Series in New York City. The "Misery" singer rocked an outfit consisting of a high-cut fishnet leotard over a bra top, which she paired with low-waist cropped pants, highlighting her killer abs.
"I just like being with her, but when she's all dolled up and we go places, it's always fun for me," Shelton told ET last month when we caught up with him at The Voice finale. "If she was here right now, not one person here would be looking at anybody else but her. It's just cool to know that's who I came here with. ... They may come up and talk to me, but it's only because I'm one person over from her. Pretty cool."
