Did Miley Cyrus's Partying Doom Her Engagement?

Pop singer Miley Cyrus and her movie star fiancé, Liam Hennsworth, have called off their engagement due in part to Cyrus's hard-partying ways, according to the New York Post. “Miley and Liam are done; it’s over. She likes to party really hard and can be pretty wild. It became a problem for him,” claims an anonymous source. Bafflingly, another source tells the Post's Page Six that it was Hennsworth's behavior—not Cyrus's partying—that caused the split. “They have broken up before, and are broken up again now," clams source No. 2. "There was drama because she suspected he had a wandering eye. And she recently tweeted a denial that he cheated." Whatever the truth of it, the "Party in the USA" singer does have a well documented pedigree as a Hollywood party girl: In 2010 a video surfaced of her smoking saliva, a hallucinogen that's legal in California. Last month, an instagram photo emerged that purportedly depicted the star smoking marijuana. She denied that the weed-smoking photo was her—but owned up to smoking salvia and apologized. “For me it was a bad decision," she admitted, "because of my fans and because of what I stand for."
