Speculation over the current status of Miley Cyrus and fiancee Liam Hemsworth has gone into overdrive since Miley's been spotted without her engagement ring. So, what's the deal?

Well, according to the New York Post, sources are telling them it's over for the couple. “Miley and Liam are done; it’s over," one source told the Post's Page Six, adding, "She likes to party really hard and can be pretty wild. It became a problem for him.”

Another source told Page Six, “They have broken up before, and are broken up again now. There was drama because she suspected he had a wandering eye. And she recently tweeted a denial that he cheated. While Miley has insisted they are still together, right now they are very, very much apart."

The rumors intensified after a photo was taken of Hemsworth with "Mad Men" actress January Jones in the back of a car after a pre-Oscars party in Hollywood. Jones has refused to answer questions regarding the rumors.

Cyrus is currently in Los Angeles while Hemsworth is in his native Australia visiting his brother's family, according to Us Weekly.
