TMZ however, reported that the pair are not yet married.

'People connected to both whom we know and trust say they're "100%" not hitched ... not yet, at least,' the website claimed. 

Other reports suggest that Liam's ring is merely a promise ring and that the couple's romance hit a rough patch in recent months.

Speaking to OK! last week, a source alleged that Liam refused to wear Miley's promise ring for the most part of this year, prompting the American songstress to question his commitment to the relationship.

'She pushed him and pushed him to wear the ring and she finally lost her temper and was screaming at him furiously. The fight was one of the worst they've had,' they claimed.

Another insider has told OK! the stress of wedding planning has also taken its toll on Miley and Liam's relationship in recent months.

'Everything became about work or the wedding. [Liam] felt like she wasn't paying attention to the relationship', said the source.

The report claimed the couple put their wedding on hold and have agreed to take a more relaxed approach to the planning process.

'Things have really turned around. Miley and Liam are so much happier now,' claimed the source.
