Cyrus and Hemsworth, who began dating in 2009 and have had an on/off relationship since, became engaged earlier this year.
'The Climb' singer Cyrus posted several images on Twitter on Christmas Day, hinting that she has tied the knot with her Hunger Games fiancé Hemsworth.
In one image (pictured above), Cyrus is seen wearing a leopard print onesie and a Santa hat and beard on Christmas Day. Her finger appears to show two rings - an engagement ring and seemingly a wedding band.
Another image that Cyrus posted on her account (pictured above) appears to show Hemsworth also sporting a wedding band on his ring finger.
Cyrus had previously insisted that her father Billy Ray Cyrus knew nothing about her wedding plans, denying his claims that she will have more than one wedding.
