Dolly Parton

The ‘Jolene’ singer - who has kept her husband Carl Dean, 81, of nearly 60 years out of the limelight - learnt the importance of keeping "something back” for herself from her mother Avie Lee before she hit the big time.

The 77-year-old country music icon said last year: "I learned early on. And I think my mama told me when I was young, ‘Always keep something back for you. You can give what you’ve got to give, but don’t give it all away. Always keep something for you.'"
