A source told OK! Australia that the 25-year-old Cyrus had repeatedly put off plans for their wedding. "He wants kids and doesn't want to keep putting it off but it's not quite the timeline Miley had in mind... he is left heartbroken," they said. "Miley put off plans for the wedding and Liam was growing tired of it... They haven't been getting along in recent months.
"[She] didn't really want to get married. It's something that everyone else seemed to get but Liam. [His] family had been begging him to see the light for a long time, but he had faith in Miley. Now he feels like an idiot."
It's believed that the split happened last week, which would make sense after Cyrus deleted every post from her Instagram. Neither she nor Hemsworth have publicly commented on their split as yet.
