Miley Cyrus has revealed that the final series of Hannah Montana will have a “definite ending”.

MTV recently confirmed that the fourth and final season is in production and will premiere in late spring with enough episodes to last until 2011.

The show, which premiered in 2006, follows the title character as she tries to lead a double life; as pop star, Hannah Montana, and a normal teenager, Miley Stewart. Season four will continue to focus on her struggle to balance both lives.

Speaking to E!‘s Ryan Seacrest on the red carpet at last night’s Grammy Awards, she said: “It’s really cool the way we’re doing it.

“It’s not like shows that end and you see reruns over and over. We’re giving it a definite ending because it deserves it.”

When asked if she was sad about leaving the character, she replied: “Yeah. Everyday I come to work we’ll get frustrated and like, ‘Is this right? Is this how we want to end it? What do we want to do?’.

“We’re like, ‘Let’s make the best decision we can as a family’. It’s so important, those last few times together, to make it the most important time, spend it with each other and love on each other.”

Disney officials also confirmed to The New York Post that the upcoming fourth season will be the last for the show that made Miley Cyrus into a superstar and put her dad, Billy Ray Cyrus, back on the map.

“You never know in this business . . . but right now we’re scheduled to wrap [forever] after shooting this new batch of episodes,” said Disney Channel Worldwide’s Adam Bonnett, senior VP/programming.

Bonnett added: “It’s one of the things she’s been wrestling with for months — whether it’s time to make a decision to continue being Hannah Montana or just be a regular, ordinary girl.”

Cyrus was recently named favorite breakout movie actress at the People’s Choice Awards, and stars in the drama The Last Song later this year, as well as playing herself in the upcoming Sex And The City sequel. The 17-year-old also introduced the Black Eyed Peas at the Grammys.
