The former couple first sparked reconciliation rumours over Christmas, when the 23-year-old pop star spent the holidays with Hemsworth and his family in his native Australia, reported Us magazine.
"The plan is for Liam to stay there while they reconnect, and then move in permanently when he's ready," a source said.
Following the reconciliation, the songstress moved back into his nearby Malibu pad.
The couple originally called off its nuptials in September, 2013 after four years together, but Cyrus and Hemsworth have spent increasing amounts of time with one another ever since the holidays.
