Miley Cyrus Twitter: Warns Billy Ray Cyrus to 'Tell the Truth' about 'Mystery Woman' DYLIS CORMAN [PHOTOS]: Dad 'Cheated On' Tish Cyrus with Sexy 'Chicago' Broadway Co-Star?

On Monday (June 24), a rather cryptic tweet popped-up on Miley Cyrus' Twitter account before she quickly deleted it. The post (directed at the songstress' dad Billy Ray Cyrus) stated, "Since you won't reply to my texts I'm giving you an hour to tell the truth or I'll tell it for you." Attached was a photo of Cyrus posing with a mystery woman... sparking rumors that the "Achy Breaky Heart" crooner actually cheated on his ex-wife, Tish Cyrus. Turns out that the "mystery woman" in the Twitpic is Dylis Corman - Billy Cyrus' former Broadway "Chicago" co-star. Hmm... wonder what that means?

Here's the tweet Cyrus posted on Monday before promptly deleting it:

Cyrus acted as if her Twitter account malfunctioned, later tweeting:

@MileyCyrus: "Wtf? My twitter was just actin all types of cray!"

But what's the real deal? As fans already know, Tish Cyrus filed for divorce from Billy Ray on June 13, 2013 citing "irreconcilable differences" after 19 years of marriage. But did the Hollywood couple break up because the popular country singer actually cheated... with Broadway starlet Dylis Corman? Cyrus starred with the redheaded beauty in the Tony Award-winning Broadway revival of Chicago back in November 2012. Perhaps the relationship was more than just professional...

Gossip Cop recently reached out to reps for both Billy Ray Cyrus and Corman for comment - no one has yet to respond.
