For some, a simple "unfollow" might not mean much, but for Cyrus, it was telling. In 2009, she quit the social media site at Hemsworth's request, and since rejoining, she's used it as a primary way of communicating with her fans (and to vent). "I am so sick of La [sic]. And sick of the lies that come with it," she wrote in March. "I didn't call off my wedding. Taking a break from social media. #draining"media: 20271286
