The 18-year-old Camp Rock star posted a message to her fans on Twitter late last week announcing the title of her new album.
'Do you guys want to know my album title?! Are you ready because I'm about to announce it…' she tweeted.
She then began a Twitter countdown before revealing the name of her new album – '#UNBROKEN!' – as well as tweeting a glammed-up photo of herself wearing a long black skirt and fur jacket.
She then started the hashtag '#Unbroken920'.
The singer-actress checked out of rehab in January after reportedly seeking help for an eating disorder, self-harm, and bipolar disorder. The title of her new album refers to her recovery.
'It's a daily journey, and it's definitely going to be a struggle that I'll have to deal with for the rest of my life,' she said.
The album is due to be released on 20 September.
