Gwen Stefani and Gavin Rossdale's split [1] still feels really fresh, but the rocker is coping by channeling her feelings into a new song. Stefani debuted "Used to Love You" at the MasterCard Priceless Surprises in New York on Saturday, saying, "I just want to share a song that I wrote recently. This song is really special. I think this is gonna be the new single." We got a short video of the new track from her performance, and now we have the full music video, shared by Stefani on Facebook [2]. Here are some of the choice lyrics: "I don't know why I cry/But I think it's 'cause I remembered for the first time/Since I hated you/That I used to love you." So . . . this is definitely about Rossdale, right? Listen below, and decide for yourself!
