The 49-year-old country singer, who has two adopted sons, Wyatt, three, and 11-month-old Levi, said that she has no fear of entering her 50s because she is young at heart.
She told Prevention magazine, 'Age is such an indefinable experience. I look at my grandmother when she was my age - she had boobs down to her waist and looked like an old lady. At 65, my mum is as fun, cool and beautiful as ever. I think it's just a state of mind.'
The Nashville resident added that she has no plans to move in the later part of her life.
'I love Los Angeles. I am so happy to see my friends there, but after four or five days, I'm like, 'Let's go home.' Nashville feels more reality-based. I feel centred there. There's a connection between me and nature,' she said.
