MILEY CYRUS and her hunky Aussie fiancé LIAM HEMSWORTH splitsville, according to a report.

 “Miley and Liam are done — it’s over,” an insider told the NY Post. “She likes to party really hard and can be pretty wild. It became a problem for him.”

A separate source told the NY tab that Miley “is a fiery character, and they do fight, but she is crazy about Liam,” and “isn’t ready to accept it might be over for good.”

Another source told the paper Liam, 23, “needed to get away from Los Angeles and spend some time” in his native Australia, where he’s been seen with brother “Thor” Chris Hemsworth, sister-in-law Elsa Pataky and niece India Rose.

Miley, in the meantime, has been working on her fourth album in LaLa Land, where she’s been seen (OH NO!) sans engagement ring.

 “They are very, very much apart” right now after Liam’s “wandering eye” had the Hannah Montana star paranoid that he was cheating on her. 

Miley’s peep’s recently tweeted a denial that he was, RadarOnline noted.
