You Can Practically Feel Gwen Stefani's Pain Watching Her Perform "Used to Love You"

A week after unveiling the music video for her new single, "Used to Love You," Gwen Stefani appeared on The Ellen DeGeneres Show to sing it in front of a live audience. The song is indisputably about her ex Gavin Rossdale. The two split over the Summer, and to be honest, we're still healing. Stefani's performance is beautiful, and it's clearly a very emotional song for her. Watch her performance, and feel her pain.
