Miley Cyrus may have thrown her father Billy Ray under the bus when she tweeted a photo of him and a mystery woman along with an ultimatum that he tells everyone -- or she does.

We're still not totally sure what that means (odds are it has something to do with BR's recent divorce proceedings), but now we do know who the mystery lady is.

So what's her story?

NAME: Dylis Croman

AGE: We're gonna say mid-30s, assuming she got her first role on the Great White Way when she was around 18 in 1996

HOMETOWN: She grew up in Dallas, where she was a member of the Dance Council of North Texas

OCCUPATION: Broadway Baby (singer, dancer and actress)

WORK: 'Chicago,' 'Sweet Charity,' 'Fosse,' 'Oklahoma,' and 'A Chorus Line' (she also appeared in an episode of the now-defunct TV series 'Smash')

WHERE THEY MET: Last year on the set of the Broadway play 'Chicago,' where Billy Ray played lawyer Billy Flynn and Croman was the dastardly Merry Murderess Mona


Here's another shot of Dylis:

Here's another video where you can see her action at around the 35 second mark:

Check out one more photo of Dylis and Billy Ray below, and get familiar with it -- because even though it was shot at a perfectly innocent cast party, if this story blows up, we're pretty sure this picture is the one you'll see in all the tabloids.
