Uh oh. Sounds like there may be more trouble in paradise after all for Miley Cyrus and Liam Hemsworth. The 'Can't Be Tamed' starlet was seen hitting the town with a bunch of bling ... but not her engagement ring from Hemsworth.

TMZ caught snaps of Cyrus out in Los Angeles last night without Hemsworth and without her ring. In its place were a few other sparklers that would make any magpie blush.

While it's possible that the 'Party in the U.S.A.' singer simply didn't feel like wearing her ring that night, it's unusual for her to have pulled such a move amid reports that her relationship is in trouble. Only a few hours before, Cyrus had issued a long, rambling diatribe of denials that she called off their wedding.

Rumors of a rift have been whispers for a while, but grew to a dull roar after the 2013 Oscars. Cyrus and Hemsworth hit parties up separately. Initially, a source denied that there were any problems between the couple, citing that they simply wanted to go to different parties -- but then Hemsworth was photographed leaving a soiree with actress January Jones (and was possibly smooching her at the fete).

However, newer reports suggest that the couple are indeed having problems, but each report varies with how severe the problems are. Some say that they're flat out over, others say they're working things out. In any case, Cyrus' conveniently timed, conspicuous lack of engagement bling has us worried.
