Miley Cyrus is allegedly preparing to leave her hit Disney show Hannah Montana.

"You never know in this business... but right now we're scheduled to wrap [forever] after shooting this new batch of episodes," said Adam Bonnett, the channel's senior vice-president of programming.

Bonnett is quoted as saying that the fourth season will premiere in late spring but that there will be enough new episodes to last until 2011.

A spokesperson for Cyrus reportedly confirmed the news to Access Hollywood.

Hannah Montana revolves around a high school student called Miley Stewart who lives a secret life as an international popstar.
