Watch Tim McGraw’s Touching Birthday Message to Faith Hill

Tim McGraw might've recovered from his recent fall off the stage, but he's clearly still falling for wife Faith Hill. In celebration of Hill's 55th birthday on September 21, McGraw (her husband of over 25 years) posted a touching tribute video on Instagram.

Set to the sounds of McGraw's song "My Best Friend," the video features a slideshow of photos of Hill, from album covers to candid behind-the-scenes shots.

"Happy birthday!!!!!" McGraw wrote in the caption. "My best friend. My soul mate. The love of my life. I can't believe that I get to spend my days and nights with you for the rest of my life! You are such a remarkable person and our 3 daughters could not have a better role model in their lives…… We love you baby!"

McGraw and Hill share daughters Gracie (25), Maggie (23) and Audrey (20), who also expressed some of their own appreciation for their mom on Instagram.
