Tim McGraw and Faith Hill are celebrating their 21st wedding anniversary with new music. On Friday (Oct. 6), the couple released a new single together, "The Rest of Our Life."

"The Rest of Our Life" is the second single from and title track of McGraw and Hill's upcoming collaborative album, due out on Nov. 17. It follows “Speak to a Girl,” which the couple released in late March; that song was written by Shy Carter, Dave Gibson and Joe Spargur and co-produced by Byron Gallimore.

"The Rest of Our Life," written by Ed Sheeran, Amy Wadge, Johnny McDaid and Steve Mac, is the first song on the project of the same name. In the piano-driven song, the two country stars sing from the point of view of a couple considering marriage.

"There’s one thing I should be giving up, giving up now / And that’s worrying about life," goes the chorus of "The Rest of My Life." "Oh, I’ll be fine if my gray hair shows / I’ll be fine if my waistline goes / I’ll be fine even if time takes its toll / We’ll stay young for the rest of our lives."

The new album from Hill and McGraw will be released through Sony Music Entertainment. Both artists signed separate deals with the company in February; per reports, their contracts each involve “multiple solo albums” as well.

McGraw and Hill -- who wed on Oct. 6, 1996 -- are currently out on the road for their 2017 Soul2Soul Tour. The trek began in early April and is scheduled to run through the end of October.
