Miley Cyrus is reportedly "freaking out" as one of her best kept secret, a diary, has allegedly gone missing, new media reports are suggesting. The 21-year-old apparently kept a journal to log in the details of her sex life and now she cannot find it. The diary reportedly has details of her love life with not only Liam Hemsworth but also with her previous boyfriends Nick Jonas and Justin Gaston, the magazine alleges.

"She's kept this diary for years. It's got vivid details about every hook up she's ever had, how all the guys compared, who was the best kisser and so on," revealed an insider close to the 21-year-old singer to Heat Magazine.

But last week, Miley realised her "secret sex diary" was not at its usual place in her house, and she "turned her house upside down looking for it." The "We Can't Stop" singer is worried about the consequences if the diary gets into wrong hands as it has very intimate details about her love life, reveals the magazine.

"Poor Miley is freaking, this would be so humiliating if it gets out," added the source to the magazine. However, Miley has been quiet about the whole issue.

Miley dated Nick Jonas of Jonas Brothers but the couple split after two years. The singer revealed to MTV in her 2008 interview that she and Nick loved each other but "argued a lot." "Maybe he'll be my best friend for the rest of my life or maybe I'll end up marrying Nick Jonas!" speculated Miley to MTV back then. She also dated Justin Gatson when she was just 15 and he was four years her senior.

But Miley's most prominent romance was with Australian actor Liam Hemsworth. The couple even got engaged to get married but the two split in September 2013. In his latest interview with Nylon magazine, the "Hunger Games" actor revealed he respects Miley's privacy and says there's not "not much to say; there's no bad blood there."

Both Miley and Liam are not officially dating anyone since their break-up, and the "Wrecking Ball" singer even confessed in a recent interview that she still loves Liam. "I love Liam, Liam loves me," said Miley in an interview on Australia's Sunday Night television show. Read more here.
