Ryan Hurd

The country star and her soon-to-be-ex-husband are putting their 3-year-old son first on Halloween.

Maren filed for divorce earlier this month — and Ryan was very surprised, a source says.

Including the official cause, her custody request, how they may split finances and belongings and why her attorney is important.

After five and a half years of marriage, Morris and Hurd are going their separate ways.

"She deserves a little sunshine for the burden she has carried for every artist and fan that feels the same way."

Take a look back at Maren Morris and Ryan Hurd's relationship captured in these sweet snapshots.

Their love story is a Nashville fairytale.

Morris is pregnant and happy in Hawaii, just begging for good virgin cocktail recipes!

Congratulations, y'all!

Oh yeah -- they're 'great ones,' alright!

You can just hear it in her voice.
