US pop star Miley Cyrus has confirmed her marriage to Australian actor and long-standing partner Liam Hemsworth. The couple tied the knot in a small ceremony on Sunday, according to reports. On Wednesday, the pop star confirmed the news in a series of Instagram posts. The couple first met on the set of "The Last Song" in 2009 and began dating and even got engaged in 2012. However, they called off their engagement the following year and stayed broken up for three more years. The stars were spotted hanging out again in 2015, and in 2016, during an interview on "The Ellen DeGeneres Show," Cyrus confirmed that she and Hemsworth were back together and engaged. Ever since, they had been low-key about their relationship. In November, Cyrus tweeted that she and Hemsworth had "made it out" safely as fire ravaged properties in Malibu.
