WATCH: Finneas and Ashe reunite on romantic duet 'Till Forever Falls Apart'

Producer/singer-songwriter Finneas and Ashe have joined forces once more on their latest duet, 'Till Forever Falls Apart'.

The new single explores how love can weather any storm, earthquake or natural disaster, accompanied by a sunset music video of the pair dancing together.

Ashe and Finneas previously linked up for her massively successful track 'Moral of the Story', which featured in Netflix's To All the Boys: P.S. I Still Love You.

"'Till Forever Falls Apart' is one of my favourite songs with one of my favourite people. If I’ve learned anything from 'Moral of the Story,' it’s that accepting the hard truth is strangely comforting," Ashe wrote in a press release on the track's origins.

"This song, while sounding like the most romantic song I’ve ever written, is about acceptance as well. The lyrics, 'I’m gonna love you knowing we don’t have forever' is about how it’s more important to have had the chance to love than to stay in love. Finneas is one of the most talented people I know and it’s fitting to release this song with someone I love so much. I'm lucky to know him and I hope to never know a life without him in it."

Ahead of the video's premiere, the 27-year-old Ashe noted that their "old school movie moment" was mainly inspired by the 1930s dance duo Fred Astaire and Ginger Rogers.

"Ashe to me, is a timeless artist. Her music will be as relevant and important 30 years from now as it is today," Finneas added in a statement. "Making music with her has always been an extension of our friendship and I could not love this song more."
