Engaged or not engaged? That seems to be the question following Miley Cyrus and Liam Hemsworth lately, with the singer's provocative twerk-full performance at the MTV VMA's fueling break-up rumors like never before, and an alleged "sexting" relationship between Hemsworth and January Jones making headlines last week. Although Liam's rep denied the texts between his client and Jones, it seems like Miley doesn't really believe that story since she has unfollowed her fiancé from Twitter. For Miley, who is an active Twitter user, this is the ultimate snub and a public declaration that there could be trouble in paradise.

However, sources report that what "really" triggered Miley's social media move this time was that she reportedly wanted to spend a rare couple of days off with Liam, but he had other plans in mind as he decided to go to Las Vegas to attend the Floyd Mayweather Jr. vs. Canelo Alvarez boxing match instead. For Miley, it was the last straw, according to an insider who talked to Yahoo! "She unfollowed him to send him a message that she's serious about being done this time. They've had fights before but they've always kept it secret, so it's been easy to go back and forth." By sending out such a public message, the insider speculates that "it took it to a whole new level."

Their relationship has been under the microscope recently with reports that the pair have split up and gotten back together numerous times in the last 12 months. And many claim the Aussie actor has been trying to break free for some time now. "They're just weeks away from calling it off permanently," a source told Us Weekly of their downward spiral. "Liam feels very distant emotionally from Miley these days." "Liam and Miley haven't officially split, but it's over ... It's just that neither wants to pull the trigger," said another insider.

Miley and Liam were last seen walking the red carpet as a couple in early August, when the 20-year-old singer supported her Australian beau, 23, at the premiere of his new film "Paranoia" in Los Angeles. However, witnesses revealed they "acted like strangers." "Miley and Liam acted like they didn't even know each other the entire night," a source told the Daily Mail. "She was wearing her ring but they acted as if they were strangers. Their kisses were awkward and he didn't seem into them."

What do you think? Are Miley Cyrus and Liam Hemsworth over for good? Or will the pair surprise us with an impromptu wedding shutting down all rumors? After all, Miley is in Paris, the capital of love, and with a new brunette do, maybe she's just preparing to make a shocking announcement to the world.
