This is getting ugly.

Miley Cyrus has taken to Twitter to threaten her dad, Billy Ray Cyrus. Miley's parents just recently filed for divorce and it's starting to seem like Twitter is the only way they are all communicating.

The most recent post by Miley directed at her dad seems to questions his relationship with another woman (see the pics here). Miley never posted "the truth" as she promised.

Maybe Billy Ray finally texted her? Or picked up the phone and called her? Either way, things aren't looking good for the Cyrus family.
