Tim McGraw and Faith Hill's oldest daughter, Gracie, turned 22 on Sunday (May 5), and her dad took the opportunity to show off how grown up and beautiful his eldest child has become.

For those who have been following the McGraw family for years, it's quite the shock to see the little girl grow into a young woman, as he displays in a photo montage on social media. Fans can see how she progresses in age to the present (where she looks an awful lot like both of her famous parents).

It's apparently shocking to McGraw himself, as he notes he can't believe his "heart and soul," the girl he describes as having "a heart bigger than the Milky Way galaxy," is 22 years old.

Gracie is a talented artist in her own right, and her father has encouraged her to pursue music. In fact, he even put her on one of his albums: The pair sing on "Here Tonight," a duet from 2015's Damn Country Music.

Gracie is older sister to Maggie and Audrey, the latter of whom turned 17 in December and will be the last child to leave the nest. McGraw shared with Taste of Country Nights last year that his wife of 22 years is having a hard time accepting that they'll soon be empty-nesters.

"It's toughest on mom, because she is the one ... they always want mom to do stuff for them. Sometimes she just misses them and doing things for them everyday and doing things moms do," he admits. "I think it’s really tough on her sometimes."
