Media reports suggest that the two stars who have been dating for a long time may have taken in the plunge in a secret ceremony.
According to the Daily Mail, Miley flew into Byron Bay, on the New South Wales coast of Australia, to spend the New Year with her fiancé.
And in Monday's NW magazine, it's been claimed that Miley Cyrus and Liam Hemsworth tied the knot in secret during the trip.
The report comes after the couple were spotted wearing bands on their ring fingers in the coastal town last week.
An insider reportedly said of the alleged nuptials: 'It's such a special place for them (in Byron Bay). It felt right.'
The A-list couple called off their first engagement in 2013, but rekindled their romance in January 2016 while ringing in the New Year in Byron Bay.
