After ringing in the New Year, the pair reportedly flew back to Australia where they were rumored to have made wedding preparations. Some sources claimed that Miley and Hemsworth's wedding will take place in Byron Bay, which is their spot in Australia.

Another source said that Miley and Hemsworth are not rushing to get married since both of them enjoy what they have right now. The source also revealed that the pair is in a healthy and stable relationship, and that they have sorted out their past issues and problems.

Miley confirmed her engagement to Hemsworth when she appeared on "The Ellen DeGeneres Show" in October.
