The 66-year-old Fleetwood Mac singer is currently promoting her latest solo album 24 Karat Gold: Songs from the Vault, which is compiled of new recordings based on demos Stevie sang between 1969 and 1987.

And upon reflection of her life thus far, the songstress believes she stressed out about far too many things as a young woman.

“Part of me is feeling extremely old now, and part of me is feeling extremely young. Because I look at these pictures and realise I worried about things that I shouldn’t have been worrying about,” she explained in an interview with Billboard magazine. “Like the fact that I had little marionette lines around my mouth when I was 29, and I was complaining about them. I wouldn’t go out to the beach without a sarong from my neck to my ankles.

“Now I see a picture of myself from that era in a bikini and I’m like, ‘You looked great. And you missed out on a lot of fun vacations, because you were so sure that you were fat.’”

Mabel Normand is one of the songs from her new LP that holds deep significance for Stevie.

The biographical tune is based on the life of the eponymous actress who died after struggling with a severe cocaine addiction.

“Give Mabel Normand a special listen. Mabel was an amazing actress and comedian from the ’20s, and she was a terrible cocaine addict,” Stevie explained. “She eventually died of tuberculosis, but it was really her drug addiction that killed her. I saw a documentary of her in 1985, when I was at my lowest point with the blow. I was watching TV one night, the movie came on, and I really felt a connection with her. That’s when I wrote the song. Less than a year later, I went to rehab at Betty Ford.”
