Billy Ray Cyrus' ex-wife Firerose trashes the singer after son Trace reveals his dad is 'struggling'

Firerose is now trashing Billy Ray Cyrus.

His ex, who was briefly and tumultuously married to Billy Ray Cyrus, 63, is speaking out after the Achy Breaky Heart singer's disastrous performance at the Liberty Ball during Donald Trump's inauguration.

She is the latest person to criticized the star after his son Trace Cyrus called him out. 

'What's being seen in public now reflects much of what I experienced in private during our relationship,' Firerose — whose short marriage to Billy Ray was followed by a messy divorce — told Page Six on Thursday.

'It's very sad to see those same struggles continue for him, but I'm glad the truth is coming to light — for his potential good because healing is only possible when you confront the truth and accept there's a problem,' the Australian singer, 25, wrote.

Billy stumbled through his performance at the Liberty Ball on Monday night, causing organizers to shut down his sound and lighting, leaving him to wander around the stage in an apparent state of confusion.

The In the Heart of a Woman singer issued an Instagram statement blaming faulty equipment.

But his family, in particular his son Trace, said he saw right through that excuse. 

Trace and his siblings are 'genuinely worried' for their father Billy Ray.

The 35-year-old star has penned an emotional open letter after his dad's performance at Donald trump's Liberty Inaugural Ball on Monday, when the country music star was seen wandering around the stage and talking to the audience, which he later blamed on technical difficulties.

In a lengthy Instagram post, Trace - whose sisters are Miley, Brandi and Noah - wrote: 'Since my earliest memories all I can remember is being obsessed with you and thinking you were the coolest person ever.

'I wanted to be just like you. The day you adopted me was the happiest day of my life.

'Sadly the man that I wanted so desperately to be just like I barely recognize now. It seems this world has beaten you down and it's become obvious to everyone but you.

'You may be upset with me for posting this but I really could care less at this point. Me and the girls have been genuinely worried about you for years but you've pushed all of us away.'

Trace said Noah has 'desperately' wanted Billy Ray, 63, 'to be part of her life', but claimed he hasn't 'even been there for her'.

He continued: 'That's your baby girl. She deserves better. Somehow just like me she still idolizes you though.'

He said Billy Ray's children were 'all hanging on to memories of the man we once knew and hoping for the day he returns'.

He added: 'You're not healthy Dad everyone is noticing it. Just like I showed up for you at mamaws funeral when you didn't expect me to I'm still here right now.

'As I write this with tears in my eyes I hope you realize this message only comes from a place of love and also fear that the world may lose you far too soon. I love you Dad.'

Trace - who revealed he has been 'clean from alcohol' for over 18 months - insisted he will keep praying for his father.

He concluded the open letter: 'We haven't talked in a while but I'm over a year and half clean from alcohol.

'Guess what? I feel amazing... I don't know what you're struggling with exactly but I think I have a pretty good idea and I'd love to help you if you would open up and receive the help.

'You know how to reach me. Till that day comes I will continue to pray for you.'
