Too cute! Tim McGraw took to Instagram on Friday, Sept. 21 to wish his beautiful wife, Faith Hill, a happy 51st birthday and posted a few TBT snapshots of the country star as a little girl and later with their family. 

“From the first time we met, I knew (she didn’t!) that she was the love of my life forever… No matter the ups and downs, the happy and sad or the good and bad. She’s so special and so loved by us. Happy Birthday, my love. When I wake up next to you in our 80s… I’ll smile at the life we’ve built,” Tim wrote next to the heartwarming snaps.

Faith and Tim, also 51, tied the knot in October 1996 and are proud parents to daughters Gracie, 21, Maggie, 20, and Audrey, 16. Since the two country singers have similar music careers, Tim and Faith previously told People that it’s not hard for them to balance their work and family life because they are constantly supporting one another.

“It’s such a rare thing to be able to experience what we do for a living, and to do it together, really feels like all the moments are special,” Tim revealed. Faith added, “I watch him perform and still to this day I’m awed by it.”

Tim also said that he could never grow tired of Faith’s angelic voice. In fact, he said he could, “listen to Faith sing all night.” But the couple knows that they still need to give each other space so their romance can remain stronger than ever. “We both have our daily routines and we have our own dressing rooms. We each have our own space to retreat to so we do get time to ourselves,” Faith shared. 

This October, Faith and Tim will celebrate their 22nd wedding anniversary — we can’t wait to see the photos they post on social media to mark that special occasion!
