Morgan Evans has released a brand-new song, "I Do" -- and, as its title suggests, it's all about the love of his life, his wife Kelsea Ballerini. Readers can press play above to hear the song.

In the feel-good "I Do," Evans uses those two sacred words not only as a wedding vow but to show the progression through which every happy relationship goes: "Yeah, girl, you're beautiful / Just takes one look to see," the Australian singer-songwriter sings. "But no one sees the side of you / That I do / Like your hair in a mess in the morning / That wake-up, no-makeup smile / That I can't believe I opened my eyes to / But I do." 

After showing a love that's growing and maturing, Evans moves on in "I Do" to explain how he hopes that love will last: "Wanna hold you forever / No, I ain't ever been so sure," he sings. "Just when I think I couldn't love you anymore / Baby, I do." 

Evans and Ballerini tied the knot on Dec. 2, just shy of one year after their Christmas Day 2016 engagement. At that time, they had been dating for a mere nine months (he even talks about the quick pace of their relationship in the lyrics of "I Do"); however, both artists say that they knew right away that theirs was a forever love.

"Wrote it about my girlfriend. Recorded it about my fiance. Releasing it about my wife ...," Evans says of "I Do" on Twitter.

"I Do" is available on iTunes now.
