Gwen Stefani has debuted her new song Used to Love You.
The singer performed the track at her MasterCard Priceless Surprises concert in New York City on Saturday evening.
It contains some pretty emotional lyrics including “you go, I’ll stay, you can keep all the memories” which suggests it could be about her recent split from Gavin Rossdale.
Back in August the couple announced that they were separating after 13 years of marriage.
