The British singers shared a clip of their single "For You" on Wednesday ahead of the debut of the movie's soundtrack.
Payne posted a compilation video on Instagram of himself and Ora in the recording studio. The pair first teased the project in December.
"We did this #ForYou! Had so much fun in the studio with @ritaora. Our new single from the #FiftyShadesFreed soundtrack drops this Friday January 5," Payne captioned the clip.
Ora plays Mia Grey in the Fifty Shades films, which are based on the E.L. James book trilogy. Fifty Shades Freed was preceded by Fifty Shades of Grey (2015) and Fifty Shades Darker (2017).
"Just to be a part of it ... I never started this industry as an actress, so to be involved in a movie non-stop is phenomenal," Ora told PopSugar in December 2016.
