Miley Cyrus signs on for another season of 'Hannah Montana'

Relax, "Hannah Montana" fans.

Disney Channel has reportedly ordered up a fourth season of Miley Cyrus' hit TV series.

Now that Cyrus, who picked up a best song award at Sunday's MTV Movie Awards, is a big fancy international movie and singing star, some observers wondered if she'd stay on the small-screen series for another year.

Here's the hook: As part of her deal for another season of "HM," she gets a long hiatus to work on her new movie, "The Last Song."

Remember, that's the movie being written just for her by Nicholas ("The Notebook") Sparks.

OMG, we can hardly wait!

BAFTA award-winning director Julie Anne Robinson will do the honors, having also directed episodes of "Big Love," "Weeds" and "Grey's Anatomy."

Naturally, Cyrus will play a rebellious teenager sent to spend a summer with her estranged dad. And trouble will be a-brewing!

The movie is due out in 2010, but Sparks' novel will be published by Grand Central this fall.

Will you read it or wait for the movie?
