Update (10/20/15): Gwen Stefani just dropped the official studio recording of her new song "Used To Love You." The Sophie Muller-directed video features an intimate close-up shot of Gwen as she lays all of her emotions bare in front of the camera. It's also the same video that Gwen played behind her when she debuted the song during her encore performance Saturday night in NYC. It's pretty clear this one is about her ex. Watch the video below and get the song on iTunes.

Gwen Stefani's divorce from Bush frontman Gavin Rossdale exploded in the media earlier this year but the former No Doubt singer made no comment on the divorce...until now. Over the weekend, Gwen performed at New York City's Hammerstein Ballroom with a 22-song set that included past hits like "The Sweet Escape" and "Hollaback Girl."

Before debuting a new song, Gwen told the crowd "I'm talking about pain and love and my real life, and I just want to say thank you for listening. And I just want to share a song that I wrote recently. This song is really special." She then dove into her new song titled "Used To Love You" where lyrics include "Never thought this would happen/Gotta let it sink in." The ballad will be her next single out later this week, according to Paper. Listen to the song above.
