Country music superstars and undisputed dream couple Faith Hill and Tim McGraw have shared the music and lyrics for their latest duet, "Keep Your Eyes on Me," the tear-jerking song featured on the soundtrack of McGraw's upcoming film, The Shack.

Both husband and wife took to Instagram to share a closer look at the song. Hill posted a photo of the track's poignant lyrics written in her own hand, while McGraw offered a glimpse of some of his musical notations.

"Keep your eyes on me / Keep your eyes on me / When it hurts too much to see / Keep your eyes on me," the couple sing on the song's chorus.

McGraw and Hill co-wrote the sweet song with songwriters Lori McKenna and Shane McAnally specifically for the film. According to McGraw, it was inspired by several moments in the film where the line "keep your eyes on me" was spoken.

The Shack, which is based on the best-selling novel of the same name by William P. Young, stars Sam Worthington and Octavia Spencer. McGraw plays Worthington's neighbor, who tries to help Worthington's character through his grief as he deals with the loss of his young daughter. You can catch it in theaters starting March 3rd and hear a snippet of the couple's duet in the film's official trailer here.
