Gwen Stefani’s “life fell apart” during her divorce from Gavin Rossdale in 2016.

The No Doubt singer looked back on the “terrible” split in a candid interview with People, published Wednesday.

“When that happened, I had to literally start over again. It was a reset of my life,” the Grammy winner, 53, recalled.

Stefani and the Bush frontman, 57, had been married for nearly 13 years and shared three children when rumors swirled that Rossdale had cheated with their nanny.

The “Voice” judge filed for divorce from her husband in 2015, and it was finalized the following year.

Stefani started dating Blake Shelton in 2015, with her gushing to the magazine about how he “changed [her] life.”

The “Sweet Escape” singer said she “didn’t see [Shelton] coming,” explaining, “This was just a big old ‘What?’ It was an amazing gift to experience love like that for the first time.

“When I [started dating] Blake, that’s when I felt home, like, ‘Oh, this is where I’m supposed to be, with this guy,’” she continued.

The couple got engaged in 2020. When they walked down the aisle the following year, the country singer, 47, became the stepdad to Stefani three sons — Kingston, 17, Zuma, 15, and Apollo, 9.

Rossdale admitted to “Not So Hollywood” podcast listeners in June that he doesn’t “really co-parent” with his ex-wife and Shelton since they are “really different people” with “opposing views” from each other.

“I think you can go one of two ways,” he explained at the time. “You can either do everything together … or you can just parent. And I think we just parent.”

While the musician and Stefani rarely speak about their split, he did tell The Sun in January 2017 that “divorce is one of the hardest, most painful things to go through.”

After calling the L.A.M.B. designer “incredible,” Rossdale said, “[Divorce] was completely opposite to what I wanted. But here we are.”

Stefani, for her part, called the breakup “months of torture” the previous year, explaining to Harper’s Bazaar how she’d been “trying to figure out [his] big secret.”

She added, “My dreams were shattered. … It was the beginning of hell.”
