MILEY Cyrus has issued her father Billy Ray Cyrus an ultimatum on Twitter demanding he "tell the truth".
The 'We Can't Stop' singer sent her father - who has split from her mother Tish - an angry tweet threatening him with an online revelation and complained she has not been able to contact by phone
She tweeted: "@billyraycyrus since you won't reply to my texts I'm giving you an hour to tell the truth or ill tell it for you. (sic)"
Miley also attached an image of herself with an unknown woman with the tweet, but she deleted the post just minutes later.
Four minutes after the explosive tweet had been erased, Miley wrote: "Wtf? My twitter was just actin all types of cray! (sic)"
The 'We Can't Stop' singer previously used the social networking site to vent at her dad Billy Ray after finding out her mother Tish had filed for divorce.
The day after her mum started divorce proceedings, she tweeted: "Since your texts and email obviously aren't working would you like to talk like this?"
The 'Achy Breaky Heart' singer did not reply.
Billy Ray, 51, first filed for divorce in 2010 but he and his wife put aside their differences as they reunited a year later.
The couple have split again, with Tish citing "irreconcilable differences" in her legal papers as the reason for the end of their 19-year union.
She is seeking full physical and legal custody of the couple's only minor daughter, Noah, 13. They also have Braison, 18, together, while Billy Ray adopted Tish's children Trace, 25, and Brandi, 23, from a previous relationship.
The actor has another son called Cody, 20, from a relationship with Kristin Luckey.
