Gwen Stefani, 51, reminded fans who she is on NBC’s New Year’s Eve special on Dec. 31. Decked out in an icy ensemble — a star-shaped bikini top with a denim jacket and jeans draped in crystal fringe, complete with silver slouchy boots — Gwen proved that she’s still got the same style and glam that made her a pop icon in the ’90s and early 2000’s. It was an appropriate outfit to sing her new single in, called “Let Me Reintroduce Myself.”
