Liam Hemsworth and Miley Cyrus

Singer/actress Miley Cyrus and her Australian beau Liam Hemsworth have been 'very happy' since they reunited in Los Angeles earlier this week, putting an end to rumours that the couple had called off their marriage after she was spotted without her engagement ring.

"Things are going well," an insider told Us Weekly, "They are happy."

The former Disney star had previously explained the real reason for her missing ring. One of Cyrus's back-up singers, Lindsey J Lee tweeted about her own engagement ring - that it was getting fixed because one of the diamonds had come loose. Cyrus responded, suggesting her ring had a similar problem.

"had to send off my engagement ring today to get fixed... one of the little diamonds fell out... I feel naked without it :( so sad," Lee posted.

"@lindseyjlee ugh that's the worst! I just had a similar situation except when it happens to me then everyone says my wedding is off," Cyrus responded.

Lee responded: "@MileyCyrus OMG that sucks! people just need to mind their own business ;) I saw first hand how happy u & Liam are... don't let them get to u"

The Hannah Montana star recently uploaded a two-minute clip in which she dances to The Wop, J Dash's new hip-hop track wearing a a unicorn onesie. She claimed that the twerking video was possibly her best received piece of work.

"I could walk out and I could sing at the Grammys," she said in an interview on Ryan Seacrest's radio show, "and I will always be bashed and I will always have haters. I haven't really seen one bad comment about the twerk video. This is the first thing. I'm like, OK, I can't sing, I can't act, I'm dumb, I'm a hillbilly, but I can twerk, so whatever."
