The rumor mill is in full effect after Miley was spotted wearing what looked like a sparkling diamond ring on her ring finger at several events (including one over the weekend) as well as in a photo she tweeted out showing a manicure she recently got.
The couple met in 2009 on the set of "The Last Song," when they took their onscreen love affair offscreen. They broke up for a short time in August 2010 and reportedly got back together in April 2011 and have been going strong ever since. The pair haven't appeared on the big screen together since "The Last Song," and Hemsworth recently kept the possibility of a Miley cameo in "Catching Fire" open-ended, simply telling MTV News, "Who knows?"
Cyrus was also on hand at the "Hunger Games" premiere, and she seemed to have a different answer: "I don't think so. I don't think so!"
Whatever the status of their relationship, Hemsworth made it clear in a recent Details magazine interview that things are great between them. "What happened happened, and we've been together two and a half years," the Aussie star said. "She makes me really happy. When you start, you want to be professional, but when you're filming those scenes with someone and pretending to love them, you're not human if you don't feel something."
