During Monday's Top Ten episode, one of The Voice's four coaches, Gwen Stefani, took the stage for an emotional delivery of her latest relationship anthem "Used to Love You." Paired with images of white roses, trees adorned with flowers and fog wandering around the stage, the No Doubt singer performed the powerful song she wrote for her recent ex-husband, Gavin Rossdale.

As one would expect, her fellow judge Pharrell Williams and new love interest Blake Shelton gave the "Spiderwebs" singer a standing ovation. Stefani, dressed in a white goddess-inspired gown had tears in her eyes as she sung the ballad's 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."

Shelton and Stefani were first seen getting cozy at a Halloween party before the two decided to make their relationship public, E! notes. The 46-year-old singer filed for divorce from Rossdale after being married for 13 years when she found out he was in the midst of a nanny cheating scandal with Mindy Mann. Shelton divorced from fellow country singer Miranda Lambert in July after being married for four years.

"The song was not written that long ago," Stefani told KIIS-FM'JoJo Wright in early November after the song's October debut. "Like, I want to say maybe a month and half ago, which is crazy. I had been writing because my life blew up. Everybody knows that my life blew up last February. I'd just been dealing with that. Unexpected. I was going along thinking that was going to be the rest of my life and it's not. I don't know what happened. I've always wanted to write music so desperately because doing it is one thing that really validates me for myself."

Stefani has three remaining members in the running to win The Voice: Braiden Sunshine, Jeffery Austin and Korin Bukowski. Catch the competition on Tuesday at 8 p.m. to see who makes it to the Top 9.
