Kelly Clarkson recently opened up about her divorce from ex-husband Brandon Blackstock and when she knew her marriage wasn’t working.

During an appearance on Wednesday’s episode of Apple Music’s “The Zane Lowe Show,” Clarkson shared that she knew in her “heart” that her marriage was coming to an end while she and Blackstock were “trying to make it work” in marriage counseling.

“‘I desperately want to make this happen,’” Clarkson recalled feeling. “But I think I knew in my heart it just wasn’t going to.”

The singer and daytime talk show host, who was promoting her new album “Chemistry,” told host Zane Lowe that she had periods of feeling “shitty” after her split from Blackstock and that her grieving process felt like a “rollercoaster.” She said that she navigated those difficult times with the help of a therapist.

“It’s very helpful to have a trained professional that knows how to kind of navigate you through rough seas,” she explained.

Clarkson and Blackstock split in 2020 after nearly seven years of marriage. The former couple share a 9-year-old daughter River Rose and a 7-year-old son Remington Alexander. They finalized their divorce last year, according to People.

The singer has opened up about how her family life has changed since the couple split.

She said on Angie Martinez’s “IRL” podcast in March that her kids sometimes say they’re “really sad” their parents no longer live in the same house.

“And I just sit there, and I’m like, ‘I get it. I’m from a divorced family as well. I get it. That sucks, you know? But we’re going to work it out. And you are so loved by both of us,’” she said.

Clarkson’s highly anticipated “Chemistry” album is due out on Friday. She told Lowe in Wednesday’s interview that the album isn’t just a “divorce or break up album” but instead a “relationship album.”

She described some of the album’s themes: “There’s stuff on there that’s like… ‘it’s hard, relationships are hard, this is worth it.’”
