The 'Wild' star was thrilled to see the '9 to 5' hitmaker performing live in Hollywood but admits all the excitement left her feeling very faint.

She wrote on her social media account: "Today's #MondayMuse?! The incomparable @dollyparton, who made my musical dreams come true last night! ... You're a legend Dolly. I will always love you! #DreamsDoComeTrue #DollywoodBowl ...

"Nearly passed out when @DollyParton said my name (sic)"

And it is likely that the 70-year-old singer will be touring for years to come as she previously admitted she has a huge back catalogue of songs as she started writing at the age of four.

She said: "I started making up songs when I was four or five. The first one I can remember was about a little corncob doll that my mother made for me and which I named Tiny Tasseltop. Mamma was fascinated by how I used to rhyme words, so she used to write them down and tell them to people. She kept shoeboxes full of songs that I wrote when I was little.

"I've probably written 5,000 songs in my career. I've had hundreds and hundreds copyrighted and recorded, but there are so many more - boxes and trunks full of them - that I'll go back and rework. I'll think: that was a great title, or a great melody, but the song is not quite there yet."
