The group released a video for the single "Cry Cry Cry" Friday on Valentine's Day that was co-directed by Johnson and Cory Bailey.
The video opens with a young couple enjoying a night out at a dance hall. The couple are shown aging together as they dance with Coldplay performing as the band in the background.
"We're in this together, baby / We're as singing is to rain / So I never, never, ever let you go," Martin sings.
"Cry Cry Cry" appears on Coldplay's most recent album, Everyday Life, released in November. The album also includes the singles "Orphans/Arabesque," "Everyday Life" and "Daddy."
Johnson, 30, and Martin, 42, have been dating since fall 2017. Martin's ex-wife, Gwyneth Paltrow, voiced her love for Johnson in the February issue of Harper's Bazaar, saying she adores the younger actress.
