As readers know, the "Wrecking Ball" singer, 25, recently moved out of the Malibu mansion that she once shared with hunky actor Hemsworth, 28.
Now, a source has revealed more on the estranged lovers splitting apart.
An insider says Cyrus has been spending more and more time at her parents' Billy Ray and Tish's house instead of the Malibu love nest she used to share with Hemsworth.
"Miley said she needed some space," the source dished. "She and Liam aren't on the best terms."
The two have had an on-again, off-again relationship, ending their first engagement in 2013 but getting back together in 2016. Back then, it was assumed that the wedding plans were back on again!
But the source said they're now arguing over when to start a family.
"Liam wants to get married and have kids, while Miley just isn't quite ready yet," the insider noted.
"He's thinking of giving her an ultimatum, but their friends don't think that Miley will cave."
As Radar previously revealed, Hemsworth has been looking at homes next to his brother Chris' place in Byron Bay, Australia, while Cyrus took her wacky toys and other possessions and moved out of the Malibu estate they had shared.
While Hemsworth owns the $6.8 million Malibu home, Cyrus had bought the ranch next door for $2.5 million.
“They’ve been hanging by a thread for months,” an insider told Radar. “Now they’re as good as broken up and there will be no wedding.”
