Miley Cyrus has revealed the moment she knew her brief marriage to longtime love Liam Hemsworth was over.

The Used To Be Young hitmaker, 30, and the Hunger Games hunk, 33, dated on/off for nearly a decade before tying the knot in December 2018.

The couple separated eight months and Liam filed for divorce shortly after, citing ‘irreconcilable differences’ as the reason for the split.

In a new TikTok, Miley revealed that she came to the decision to leave her husband during her headlining gig at the 2019 Glastonbury Festival in England.

‘Glastonbury was in June, which was when the decision happened that me and Liam’s commitment to being married just really came from, of course, a place of love first — because we’d been together for 10 years — but also from a place of trauma,’ the Hannah Montana alum began.

Just before their wedding, the couple lost their Malibu home to the devastating Woolsey Fire — which claimed the lives of three people and destroyed 1,643 structures in November 2018.

Miley explained that her and her ex were ‘just trying to rebuild as quickly as we could’ but it ultimately did more harm than good.

When she took the stage at Glastonbury the following year, she came to the realization that ‘it was no longer going to work in my life to be in that relationship.’

Miley had found herself burying her emotions and, instead, assuming a false persona for the sake of her devout fanbase — something she’s now aims to avoid.

‘That was another moment where the work, the performance, the character came first. And I guess now that’s why it’s so important to me for me to not be the case [anymore],’ said the Bangerz singer, adding: ‘The human comes first.’

Miley recently opened up about their ‘magical’ home in Malibu, telling fans: ‘That house had so much magic to it that it ended up really changing my life.

The singer went on to note that she recorded her debut 2007 album, Meet Miley Cyrus, at the house, where producer Matthew Wilder was living at the time, not knowing the house would be hers years later.

The record helped Miley bridge the gap between her solo music career and her starring role on Disney Channel’s Hannah Montana.

‘The Meet Miley Cyrus record was really where I started writing my own songs as a solo artist,’ Miley explained.

‘I was working with a producer in Malibu that lived in a house in Ramirez Canyon, which I would’ve never known 15 years later I would be living in that house, which would eventually burn down,’ she shared.

Miley previously referenced the home in her song Flowers, released in January, which fans believe is about her relationship with Liam.

The star released the very racy music video for the song on her ex’s 33rd birthday.

The pop song’s lyrics allude to her failed relationship with the Aussie hunk including a double entendre about Miley watching her marriage and the Malibu home they once shared ‘burn’ to the ground.

‘We were right / til we weren’t / built a home and watched it burn,’ she sings.

When the fire happened, Cyrus was in South Africa filming Black Mirror, while Hemsworth was home and was able to rescue their numerous pets.

Following the fire, Hemsworth shared a heartbreaking glimpse at the remains of their beloved Malibu residence.

He posted a photo that showed a scorched ‘love’ sign laying amid burnt rubble from the house.

In 2019 she spoke about the devastating experience to Vanity Fair.

‘I’ll never be happy that all those memories and pictures and things that I’ve loved are gone. But to have an experience like this — I find myself feeling more connected to being human again.’

As part of her Used To Be Young series on TikTok, Miley recently recalled the chemistry she had with her ex-husband while filming The Last Song in 2009. Miley was 17 and Liam was 19 when they met.

She gushed about how their off-stage romance made their coming-of-age drama, based on the novel by Nicholas Sparks, ‘feel so special.’

‘In 2008, I needed to do another feature film for Disney and I didn’t want it to be a part of Hannah Montana,’ she told her followers. ‘Once we had written the screenplay, it was time to audition all the guys who would play Will, my boyfriend in the movie.’

After narrowing down the pool from thousands, the Malibu hitmaker said ‘Liam was a part of that final three.’

‘I think one of the elements that made that movie feel so special was it was watching two very young people fall in love with each other, which was happening in real time and in real life,’ she continued.

The two-time Grammy nominee gushed that their ‘chemistry was undeniable’ to viewers.

‘That was the beginning of a long 10-year relationship,’ she mused, referring to their passionate, on-and-off relationship, which led to two engagements and an eight-month marriage.
