Miley Cyrus’ upcoming album features a song co-written by her godmother and country music icon Dolly Parton, the singer reveals on “The Ellen DeGeneres Show” this week.

In a pre-taped episode airing Thursday, Cyrus dishes on her new album, Younger Now, and talks about the one and only song that features a co-writer.

“[Dolly and I] wrote a song called ‘Rainbowland’ last week, actually before Hurricane Harvey,” she explained.

“We are rainbows, me and you, every colour, every hue, let’s shine through,” Cyrus sang, offering a preview of what is sure to be one of the album’s most highly anticipated singles.

“What a co-writer [Dolly] is to have. You learn so much,” she added.

Cyrus’ appearance was also an opportunity for her to bridge the gap between Ellen and millennials. The pair took part in a lesson titled “Mileyennials and Me”, which shed light on Cyrus’ generation’s love of Instagram food photos and why they like “dirty music festivals.”

Younger Now is set to drop September 29.
