Looks like Liam Hemsworth's brothers got their wish. A few weeks after Chris and Luke Hemsworth staged an intervention with their younger sibling to voice their concerns about his engagement to fiancee Miley Cyrus, the Hunger Games actor has called it quits with the former Disney star, multiple sources reveal in the new issue of Us Weekly.

"They are definitely over," one insider tells Us of the ex-lovebirds, who met on the set of The Last Song in 2009 and got engaged in June 2012. (Hemsworth, 23, proposed with a 3.5-carat diamond ring, which Cyrus, 20, has worn on and off ever since.)

The split comes after months of back and forth between the two, including a recent public display of affection at a party at the "Can't Be Tamed" singer's L.A. home. Prior to that, the couple of nearly four years took some time apart and put their wedding plans on hold while Hemsworth regrouped in his native Australia.

For much more on the pair's breakup -- including details on the couple's "awkward" living arrangements, how Cyrus' "childish" rebellion tore them apart, and why Hemsworth's family is so relieved -- pick up the new issue of Us Weekly, on stands Friday.
