The former Hannah Montana star's representative has confirmed the sad news to E!, explaining the couple has ended its almost four-year relationship.
Hemsworth and Cyrus met and fell in love while filming The Last Song in 2009.
After briefly splitting in 2010, the couple reunited and became engaged in 2012.
Last week, rumours resurfaced about a romance between Hemsworth and January Jones, but his representative denied the reports calling them "tabloid fiction."
On Saturday, Cyrus stopped following The Hunger Games star on Twitter.
The couple was last spotted together last month at the Los Angeles premiere of Hemsworth's movie Paranoia.
