Miley Cyrus' claims that she and fiance Liam Hemsworth aren't on the rocks are getting harder and harder to believe. Especially when she goes out in public without her engagement ring after rumors flew recently that her husband-to-be cheated on her with January Jones at an Oscar party.

She was seen in public without said bling -- and while she was wearing rings on that all-important finger, the one that really mattered was conspicuously absent.

That's definitely not helping quell the whispers, no matter how often the non-blue-haired Miley jumps on Twitter to say that her wedding plans are still in place.
