The 'What You Waiting For' hitmaker was "devastated" when her relationship started crumbling but channelled all her negative feelings into songwriting.

She said: "I just think what happened was: In February, my family fell apart. It was devastating. I didn't know what to do. It was a real big secret but I'm not good with that. I tried everything to fix it.

"By June, I went into the studio and started writing. I was praying. I had already started on a spiritual journey when I got pregnant with Apollo that was sort of like, 'Wow, really? I'm gonna be blessed with a baby... now?' That was a miracle. It just started me on this spiritual journey and thank God it started then because I was prepared when I had the tragedy. I had that nest of spirituality in me."

The 46-year-old singer - who has sons, Kingston, nine, Zuma, seven and Apollo, two, with Gavin - was even more hurt by the split because she had dreams about having a perfect relationship like her parents.

She added to PrideSource: "My whole life all I wanted to do was be a mother and a wife, and I had the dream of having this family because that's what I had. I have parents who've been married since high school, who are in love, and they're still in love and having their big wedding anniversary.

"I had a perfect example, so it's super tragic for me. My dreams are shattered and I feel so embarrassed about what happened. I don't feel embarrassed to talk about it though, with respect to my kids."
