Billy Ray Cyrus has filed for divorce from Firerose.

Less than a year after the pair got married in October 2023, the 62-year-old country star filed for divorce from the singer — whose real name is Johanna Rose Hodges — in Nashville on May 22, according to documents obtained by PEOPLE.

The court documents cite irreconcilable differences and inappropriate marital conduct as the reason for divorce, while Cyrus is also seeking an annulment on the grounds of fraud.

At the time of publication, Cyrus and Firerose, 37, do not follow each other on Instagram.

Reps for Cyrus and Firerose did not immediately respond to PEOPLE’s request for comment.

TMZ was first to report the news.

Firerose and Billy Ray Cyrus perform in Nashville in August 2023. 

The two musicians were friends for years before they began writing songs together during the COVID-19 pandemic. They started dating in 2022 and got engaged later that year before tying the knot in October 2023.

“10/10/23 will always be the beautiful, joyous day that our two souls united as one in holy matrimony,” they wrote in a joint Instagram post at the time. “It was the most perfect, ethereal celebration of love we could have ever imagined.”

Together, they’ve released four collaborative songs: “New Day,” “Time,” “Plans” and “After the Storm.” Upon the latter track’s March release, they spoke to PEOPLE about how its hopeful meaning resonated with them, with Cyrus describing “After the Storm” as “powerful and timely.”

Firerose said at the time, “Only by the grace of God did I survive my darkest nights. There is so much truth in these lyrics and it’s my purpose to help others find strength in their toughest hours.”

In August 2023, the pair performed “Plans” on Good Morning America and spoke about their relationship.

“We’re kind of like… It’s a peanut butter and jelly,” said Cyrus. “I’m a left-handed singer-songwriter from Flatwoods, Kentucky, and she’s a trained orchestral musician…”

Firerose added, “It has been a beautiful whirlwind and I’m just so grateful that I get to live my dreams every day with the love of my life.”

In February, Cyrus celebrated Firerose’s birthday with a sweet Instagram post, calling her the “beautiful love of my life” and sharing a sweet video of them posing in front of a barn.

Firerose marked their six-month wedding anniversary in April by sharing throwback photos from their nuptials to Instagram and writing, “6 months ago I married this man. 🤍 Life isn’t always easy… but it sure helps when your husband’s also your best friend. Thank you Lord!”

Cyrus was previously married to Tish Cyrus for 28 years. The ex-spouses share five children: daughters Miley, Noah, and Brandi, and sons Trace and Braison. Billy Ray also shares son Christopher Cody with Kristen Luckey, whom he dated before meeting Tish.
