Gwen Stefani is moving on from her marriage to Gavin Rossdale!
The 46-year-old singer — who announced her divorce from Gavin, 49, in August — debuted her new song, "Used to Love You," over the weekend during her MasterCard Priceless Surprises concert in NYC.
"I just want to share a song that I wrote recently," Gwen told the crowd before performing her latest single. "This song is really special."

With emotional lyrics including, "I guess nobody taught you how to love," and, "You go, I’ll stay, you can keep all the memories," it's no secret Gwen's new song is about her 13-year marriage to Gavin!
The couple — who married in September 2002 — are parents to three sons, Kingston, 9, Zuma, 7, and Apollo, 20 months. Gavin is also a father to a 26-year-old daughter, Daisy Lowe, from a previous relationship with British fashion designer Pearl Lowe.
