Miley Cyrus mistakenly tweeted a personal conversation to her followers Thursday, then lied and said she had been hacked, before admitting the texts were hers. In a chat via text, the 20-year-old wrote a friend named “Fefe,” who may be singer FeFe Dobson, “I’m miserable…Been crying myself to sleep. Taking a zanny trying to pass out….Goodnight.” [[nid:1360629]]

Zanny is slang term for the drug Xanax, which is used to treat anxiety. The young singer was recently dubbed the Hottest Woman of the Year by Maxim magazine, and her latest song, “We Can’t Stop,” is climbing music charts. But she could have anxiety related to her relationship with actor Liam Hemsworth. Though the pair is engaged, and Cyrus continues to wear her engagement ring, the couple was last seen together last month, on a movie date. Prior to that, they had not been photographed together in five months.

They were supposed to get married in June, but they postponed their wedding indefinitely back in April. The Australian actor’s family seems unsure if the wedding will happen at all. “I don’t know,” his sister-in-law Elsa Pataky told “Life & Style.” “If they get married, it would be nice to go [to their wedding].” Hemsworth proposed to Cyrus in May 2012 with a 3.5-carat diamond ring. They began dating in 2009 after co-starring in the film “The Last Song.”

When Cyrus realized the text conversation was on her Twitter page, she immediately stated that someone hacked her account. "Someone has hacked my twitter. I'm back in action now! Wtf! If that sh-t!"  But then she admitted she mistakenly posted the conversation. "Never mind. Realized I'm just an idiot & somehow I butt tweeted my conversation. Missing home #foodpoisoningsab-tch,” the singer wrote.
