Filed under "news we all sort of saw coming," Miley Cyrus and Aussie hunk Liam Hemsworth, who've been engaged for just under a year, are reportedly kaput.

The New York Post reports that according to multiple sources, Hemsworth's trip to Australia was part of giving himself and Cyrus a break from one another ... for good.

"He needed to get away from Los Angeles and spend some time with his brother and friends,” a source told the paper.

Another source added, “Miley and Liam are done; it’s over. She likes to party really hard and can be pretty wild. It became a problem for him.”

Yet another insider said, “They have broken up before, and are broken up again now. There was drama because she suspected he had a wandering eye." She wasn't the only one who suspected it -- the rest of the world seems to agree, or at least they're giving the dude some serious side-eye about his interactions with 'Mad Men' star January Jones.

Other reports suggest that Cyrus, 20, wasn't treating 23-year-old Hemsworth well in general, and that her excursions without her engagement ring were just to piss him off and get media attention.

“She knew that it was going to cause a scene, as much as she says she hates all the talk, she actually loves it because it will get Liam to see these pictures and have him see her more. She is playing games against the media and Liam.”

Unfortunately for Cyrus, her alleged hard-partying ways may have made her a bit delusional about the state of their union. She's denied previous rumors of a split, but it's getting harder to believe her.

“Miley is a fiery character, and they do fight, but she is crazy about Liam," another source reported. "She isn't ready to accept it might be over for good.”
