It's been an emotional year for Gwen Stefani after her split from Gavin Rossdale, but Blake Shelton's girlfriend tells ET that the tough times she's endured have only helped her "write the truth" in her music.
The 46-year-old rocker's ballad, "Used to Love You," is climbing the charts, and she couldn't be more pleased that fans are relating so strongly to her very personal lyrics. "If you tell the truth and you're just honest, people pick up on that," Stefani told Elvis Duran during their ET interview on Thursday. "Humans like that."
She added, "I think the good thing is that something good is coming out of something horrible."
Stefani also spoke with Duran on his Z100 morning show, and opened up even more about what led her to penning this latest breakup track. "When I wrote the song, I was sorta in a phase of forgiveness," Stefani shared. "In a way, I'm getting to this point now, and all the songs up to that point were like, 'Rah, I'm like so upset and so crazy.'"
Stefani insisted that she never imagined she'd be divorcing Rossdale, the father of her three children. "Everybody knows, pretty much, what happened to me. I got a divorce, which completely was not in the plan at all," she explained. "For me, it purely wasn't and [it was] a shock and horrible, a crazy explosion in my life."
The No Doubt frontwoman said the last thing she wanted to do was make music after her breakup. "I had to force myself to go to the studio because I really wanted to be in bed crying," she recalled. "That's what you want to do when your life falls apart."
Stefani is certainly making the best of her situation. On this week's "The Voice," the musician brought Shelton to his feet with her emotional performance of "Used to Love You."
"The nerves were really like, 'OK, I'm gonna get naked right now and I'm gonna tell everyone what happened to me,'" she told ET. "And that's what it felt like. It felt so raw."
ET also caught up with Shelton moments prior to Stefani's performance, and he couldn't help but gush over his girlfriend. "I'm thankful for Gwen for tons of reasons," the 39-year-old country crooner said, "but mostly because she makes us all look a whole lot better on this show."
