Kelly Clarkson has revealed she lost hundreds of thousands of dollars, maybe even millions by refusing to share a song-writing credit with Dr. Luke on her 2009 single "My Life Would Suck Without You".

She told Z100: "I was making a point to the people working with me, going, 'This is how much I didn't want to do this.' I don't care about the money. I don't care about, oh, 'You're going to be the most famous person ever if you do this.' That's not what holds weight in my life.

"I was like, 'I don't want my name near his. I want to pretend this didn't happen in my life and I want to forget it.'"

In 2016, Clarkson said that RCA (owned by Sony) said they would not release her album unless she worked with Dr. Luke. She said:

"Basically, they were gonna sit on my record unless I did what they wanted. I was so frustrated because I literally said, 'Anyone in the world but this one person. I will work with anyone you want to put in my path.' I love people. I think that's apparent. I think I'm a nice person, that's apparent. It was just this one thing, and I asked not to work with Dr. Luke just because I had not a good experience with him.

"If an artist like me, I generally love everyone. You have to really be a special kind of... for me not to like you.

"My Life Would Suck Without You" reached No. 1 in America, UK, Canada, Hungary and Poland (Digital Songs).

The American Idol winner releases her 8th studio album, "Meaning of Life" on October 27, and will be commencing a world tour in 2018.

The first single from the album, "Love So Soft", was released on September 7.
