Gwen Stefani [1] 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 [2] this year. That same day, Gwen debuted her new song [3], "Used to Love You," which seems to reference her split from Gavin Rossdale [4], at the MasterCard Priceless Surprises event.

The chic outing comes during a pivotal time for Gwen, who announced her divorce from Gavin [5] in August. After stepping out without her wedding ring [6] in LA, she had a cute little date [7] with her son Apollo, and on her birthday, she proved that she hasn't changed much [8] since the '90s. Read on for more of Gwen's NYC outing, then check out all the celebrity couples who've broken up [9] this year.
