Their official status is engaged, following Cyrus' announcement last June. But she was sporting a mysterious ring on that finger for months before her beau Hemsworth popped the question with a 3.5 carat Neil Lane sparkler. Cyrus has never been one to shy away from the public eye, but she's kept her romantic life mostly private (not, however, her daily Pilates workouts and cropped T-shirts). Plus, she memorably called Hemsworth her "hubby" in a recent issue of Cosmopolitan. Just Miley bein' Miley, or Miley bein' married?
