Happy birthday, Faith Hill [1]! The singer turned 51 on Friday, and to celebrate, her husband Tim McGraw [2] shared a handful of personal photos on Instagram. While we can't get enough of the little glimpses of young Faith holding a guitar and playing sports, it's Tim's sweet message that really left us grinning from ear to ear. "From the first time we met, I knew (she didn't!) that she was the love of my life forever . . ." he wrote. "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 80's . . . I'll smile at the life we've built." Are you swooning yet?

Read on to see even more cute moments between the couple ahead.
