Miley Cyrus has called Liam Hemsworth her "boyfriend" despite flaunting a massive diamond ring on numerous occasions. The development comes at a time when rumours suggest that the couple could be planning their wedding.

During an interview with Elle magazine for its October issue, the Wrecking Ball hit-maker called the Aussie hunk her "boyfriend" despite reports suggesting that two are engaged. Although, the songstress did not call The Hunger Games actor her fiancé, she did sport the diamond ring for the magazine's photo shoot.

However, a source has told HollywoodLife that the 23-year-old singer has been casually calling Hemsworth her "fiancé" and "husband" on the set of talent show The Voice, but as soon as she utters the words, she goes on to correct herself and says that the 26-year-old actor is her "boyfriend".

Previously, it was reported that Cyrus and Hemsworth have not tied the knot but are "living like they are on a honeymoon". Subsequently, there were rumours that the couple were planning their wedding ever since the two rekindled their romance in December 2015.

"Miley and Liam are not yet married but they are living like they are on a honeymoon. They have been happily hanging out in their Malibu love shack and have been surrounding themselves with close friends and family. They are spending quality time together, sneaking away periodically but spending most of their time at home and in love," a source previously told HollywoodLife.

"Liam is between gigs and has been enjoying his hiatus with Miley. He has been spending most of his time by Miley's side. They have been going with friends out to dinner, have been really happy and are waiting on the wedding," the source added.

In early September, reports claimed that the couple got married in a secret ceremony at their Malibu home in front of friends and family. The pair started dating after meeting on the sets of the movie The Last Song in 2009, but split in 2013 after getting engaged in 2012.
