Tim McGraw's birthday wish to wife Faith Hill isn't fancy, but it's perfect. The singer turns 50 on Thursday (Sept. 21), and her man didn't let a minute tick off the clock before recognizing it.

Hill's husband of almost 21 years starts by reminding her she's the most beautiful girl in the world. "You are the most remarkable person that has ever been in my life," he adds on Instagram. "Our daughters could not have a better role model I am truly in love with you more everyday."

"Can't wait to see what "the rest of our life" has in store for us," he captions at the end of a close-up picture of Hill awash in sunlight. Le sigh.

Have Tim and Faith Ever Taken a Bad Pic Together?

Hill's birthday might actually be a workday, as she's currently producing a new Kellie Pickler-hosted TV talk show called Pickler & Ben and touring. On Thursday night the Soul2Soul Tour will stop in Wichita, Kan. She and McGraw have dates scheduled through October and are said to be working on a full collaborative album for Sony Music Nashville. "Speak to a Girl" was the first single from the project, which was originally slated for late 2017. Little has been said about it in recent months.

Hill seems to have no qualms about tuning 50. During a recent concert, she spoke out about how good she feels, saying, "Put a 25-year-old girl standing next to me and I'll tell you what, I'll give her a run for her money!"
