AceShowbiz - Kelly Clarkson experienced an "extraordinarily hard" level of depression and grief after her marriage ended. The "Breakaway" hitmaker launched her latest album "Chemistry" in June and was grateful to have an "outlet" to express her feelings in the wake of her split from Brandon Blackstock - the father of her children River, nine, and seven-year-old Remington - after almost seven years of marriage because it helped her to "take [her] power back."

"I didn't see it other than, 'This is my outlet.' I'm a let-go person; I don't hold grudges. So it was really delving into what happened in my life and why - and what am I going to do about it?" she told People magazine.

"I cannot express how appreciative I feel for having that kind of healthy outlet. Because the level of depression and things that come with divorce or grieving is extraordinarily hard. You feel alone, and it's just a blessing to be able to have that outlet for those emotions that are overwhelming."

"[Realising it was] like, 'I'm taking my power back.' That sounds very therapy, but that's because I love therapy, and I think it's important to have those tools to navigate your life and relationships."

The 41-year-old talk show host has relocated to New York City and is thankful she's been able to have a fresh start. She said, "Sometimes you don't know what life has in store for you, and you think your life is going to go one way, and it's OK that it doesn't. You never know how beautiful that might be."

In August, Kelly's children joined her on stage at her Las Vegas residency, with River duetting on "Heartbeat Song" and Remington dancing for his mom as she sang "Whole Lotta Woman", and the singer couldn't have been more proud.

She said, "They were a little nervous, but it was their idea, not mine... I was like, 'I feel like how you're looking at me is how you watch 'Spider-Man'. It caught me completely off guard, and it was the most magical moment because they were so happy and at ease. They were just in awe."
