Gwen Stefani Is All Smiles After Debuting Her Breakup Song

Gwen Stefani was all smiles in NYC on Saturday night. Gwen, who turned 46 earlier this month, kept things cool in a cutout top and black leather pants, adding to her series of flawless appearances this year. That same day, Gwen debuted her new song, "Used to Love You," which seems to reference her split from Gavin Rossdale, at the MasterCard Priceless Surprises event.

The chic outing comes during a pivotal time for Gwen, who announced her divorce from Gavin in August. After stepping out without her wedding ring in LA, she had a cute little date with her son Apollo, and on her birthday, she proved that she hasn't changed much since the '90s.
