Gwen Stefani is dealing with her breakup from husband Gavin Rossdale the best way she knows how -- through song.
The Voice coach, who split with her husband in August, debuted a new single during her MasterCard Priceless Surprises concert in New York City on Saturday, and fans got a priceless surprise.
"I just want to share a song that I wrote recently," Stefani, 46, explained to the crowd. "This song is really special."
She then started singing her melodic, melancholic new single, "Used to Love You."
With lyrics that include "I guess nobody taught you how to love," and, "You go, I’ll stay, you can keep all the memories," it’s not difficult to see how it might be about the 49-year-old rocker.
In her divorce petition, filed in August, the No Doubt lead singer cited "irreconcilable differences" and asked for joint custody of the couple's three sons: 9-year-old Kingston, 6-year-old Zuma and 1-year-old Apollo. Here's more on Gwen and Gavin's split:
