Miley Cyrus unfollowed Liam Hemsworth on Twitter last week, suggesting that all may not be well with the supposedly engaged couple. The two have made headlines over the months after not being seen together regularly, and there have been reports that Hemsworth cheated on Cyrus with actress January Jones.

Last week, the 23-year-old Australian “Hunger Games” hunk allegedly sexted the blonde beauty, saying, “I want to [expletive] you,” according to Us Weekly. Hemsworth’s rep later denied the allegation. But even earlier this year, there were rumors that he cheated on Cyrus, 20, with the “Mad Men” star, as she was photographed with Hemsworth in the back seat of an SUV at the Oscars on Feb. 24. They reportedly made out at a house party that night.

Hemsworth proposed to Cyrus in May 2012 with a 3.5-carat diamond ring, but it's been speculated for months now that the relationship is in deep trouble. They began dating in 2009 after co-starring in the film “The Last Song.”

The two have rarely been spotted out together as of late, and Hemsworth was not at the MTV Video Music Awards Awards last month when Cyrus did her raunchy performance of “Blurred Lines” alongside Robin Thicke. Wearing latex underwear, Cyrus stuck her tongue out as she "twerked" on the 36-year-old, nuzzled his neck and touched his groin with a giant foam hand.

While Cyrus unfollowed Hemsworth on Twitter, he still follows her there.
