Miley Cyrus has said that leaving Hannah Montana will be "bittersweet" for her.
The last episode of her popular TV show will go out in March 2011, after five years on air.
"It's like my security blanket, my comfort zone: I know that's where I'm going to be from 8.30am to 6pm," she told The Telegraph newspaper.
"I've always had the show to lean on, and to not have it to lean on in the future will be different for me."
But Miley has already made two films - Hannah Montana: The Movie, and now The Last Song - which is where she met her boyfriend, Australian actor Liam Hemsworth.

She said she thought they would be really different at first.
"But I went to Australia to visit him and his family and I was like, 'Omigosh, this looks like Nashville.' There were like cows everywhere. I am like, 'how are you from the opposite side of the planet and your world looks just like mine?'"
As well as her budding film career, Miley has lots of other projects to work on. She's already had a hit album and sell-out tour too.
But the teenage star admitted she doesn't always make the right choices.
"Every career thing I do can't be perfect and sometimes my decisions are wrong," she said. "I always say the minute I stop making mistakes is the minute I stop learning, and I've definitely learned a lot."
