Some of the song’s powerful lyrics include: “I don’t know why I cry / But I think it’s cause I remember for the first time / Since I hated you / That I used to love you / I thought I was the best thing that ever happened to you / I guess nobody taught you how to love.”

After nearly 13 years of marriage, Gwen and ex Gavin Rossdale announced their divorce in August.

Gwen has been serving as a judge on NBC’s The Voice alongside Adam Levine, Blake Shelton, and Pharrell.
