Terri Clark lost her beloved mother to cancer Sunday night (April 4). "She is finally at peace and out of pain, our hearts are broken, and we will miss her terribly," the singer writes on her website.

As Terri grieves her loss, our thoughts and prayers go out to her.

"She's been such a huge part of the inspiration behind everything I'm doing now and everything I've done up until now," Terri told the Edmonton Sun of her mom last September. "If you think about the person closest to you, who has been your whole life, the one person you can't imagine not being here -- almost an extension of you, that would be my mother for me."

When The Boot sat down with Terri for an interview back in 2007, just after her mother had been diagnosed with cancer, it was evident that the two were extremely close. "I know for sure that my mother loves me," she answered when asked what the one thing is in this world that she knows for sure. "And one thing I know for sure is if you don't have your health, you have nothing. This is the most important thing. You can have all the money and all the fame and all the golden nuggets that the world has to offer, but if you health goes downhill, what can you do?"

Terri's mom had a profound influence on her daughter's life, both personally and professionally. In fact, her mother's battle with cancer was the inspiration behind a lot of the songs on Terri's new album, 'The Long Way Home,' which she self-produced and put out without a major label's backing.

"When you see someone fighting as hard as my Mom was, it strikes you the things that matter," Terri told The Boot last summer. "To her, life was everything. It was about personal integrity, her family, the things she loved about living ... and I realized I couldn't make my music for any less. My fans deserved that from me, especially after the stories they tell me about things my music's gotten them through over the years."

Fans can send Terri a message of support through her Twitter page or official website.
