Disney to Miley: Face the Music or Else!

TMZ has learned Miley and Billy Ray Cyrus want off "Hannah Montana," and their conduct has triggered a war on the set.

Our spies on the set tell us Miley has bragged that she will get fired, making it clear she wants to focus on singing and not the show. For his part Billy Ray has also made it clear that there is more money in singing than a Disney cable show. As a result, the father-daughter team has been showing up to the set ridiculously late, stalling production and infuriating cast and crew.

Emily Osment, who plays Lilly Truscott, used to be extremely tight with Miley. Now we're told Emily is so bitter she literally turns away from Miley after each scene. We're told Emily's dad got in a screaming match with Billy Ray, complaining he and Miley were unprofessional.

Sources tell us Billy Ray has told people on the set that he and Miley will do twelve more episodes and then they are out. Disney was so pissed they called his agent, railing that Billy Ray and Miley were ingrates. Disney insisted that Billy Ray and Miley not only finish the twenty-four episode season -- but Disney was adding six more episodes.

To put it mildly, this set is far from the happiest place on earth.

This sounds true, Miley's made it clear she doesn't want to continue the show for much longer.

Her new album is already proving that she doesn't have the full fanbase she does from Hannah Montana. The Hannah Montana 2 Soundtrack has sold 3,140,000 copies, while "Breakout" so far has will only pass 900k next week, factoring in holiday season sales (5 weeks) in November-December, even if she were to sell 200k every week (which is VERY unlikely), she'd only just pass 2 million in total sales.
