Firerose has made shocking new claims of abuse and manipulation against estranged husband Billy Ray Cyrus.
The two musicians are currently embroiled in a bitter divorce in which they have alleged abuse on both sides following just seven months of marriage.
Now, 36-year-old Firerose - real name Johanna Rose Hodges - has elaborated further, alleging Cyrus, 62, had “strict rules” during their relationship.
In a new interview with Page Six published on Sunday, Firerose has accused the Achy Breaky Heart singer of “systematic isolation” and said she “couldn’t find the courage to leave.”
“Billy had very strict rules,” she told the outlet. “I didn’t have a car. I was only allowed to go to the local chiropractor and allowed once a month to get my nails done.”
The Australian native further claimed that the dad-of-five had kicked her out of their Tennessee home on the same day she was meant to have a double mastectomy. She had recently been diagnosed with the BRCA1 gene, which means she is at high risk of developing breast cancer.
She also expressed her fear that as divorce proceedings continue, Cyrus may attempt to use her past against her.
Last month Firerose celebrated eight years of being sober online, but said she expects her estranged husband to bring up events of the “very dark years” before her sobriety.
“I think he will use every single thing against me,” she said.
On the same day the Page Six story was published, Cyrus took to his Instagram account to share a cryptic message.
“Happy Sunday everybody!”, he penned, adding: “I’m sure very soon the truth will be revealed”.
The Standard has contacted a representative for Billy Ray Cyrus for comment.
Cyrus - who is the father of singer Miley Cyrus - initially filed papers in a Tennessee court on May 22, citing irreconcilable differences and “inappropriate marital conduct”.
He was further seeking an annulment due to alleged fraud on Firerose part, saying in the filing that he would not have married Hodges “had he known” about the alleged fraud.
According to papers viewed by TMZ, he gave her a deadline of May 24 to leave his home while also initially putting up $500/night over a period of ten days for temporary housing.
The US news outlet then reported that Cyrus is set to pay Firerose $5,000 (£3,922.90) per month for her to find suitable housing in Tennessee for 90 days or until the divorce is finalised.
