Miley Cyrus may go to college in 50 years.

The 17-year-old star is preparing for the end of her Disney TV show 'Hannah Montana' but as she wants to continue working in movies and music, can't see the point in finishing her education yet.

She said: "My sister went to college for two years and then decided she wants to be a musician and now she is a musician.

"I just already know what I want to do and if there is ever a time where I want to go back, I can.

"I learned that from my grandma. She went to college at 67 and graduated at 70 and was a teacher from then. She's 77 now, so you can go whenever you want."

Miley recently splashed out on a $3.4 million Los Angeles property that she will move into when she turns 18 in November and can't wait to have her own space.

She added: "I've bought my house and I want to decorate it the way I want and I think I worked really hard to be able to have a place that is purely my environment and exactly the way I envision - kind of like a serene, tranquil place that can just be my space."
