The country singer, who is now breast cancer free, said she adopted her sons - Wyatt, now six, and three-year-old Levi - because she realised having a family did not have to occur in the conventional way, reported Contactmusic.
"I began the adoption process right after I finished my radiation treatment. I always felt like I was meant to be a mom, but I'd been stuck on how I was supposed to do that...
"I moved to Nashville, closer to home and many great friends. I adopted my children. (Adoption) was not about me wanting a man. I wanted children. I finally realised there was no need for me to keep trying to bring a kid into the world when there are already for many great kids in the world looking for their people," she said.
