Miley Cyrus is barely 18 years old but she has been making a lot of money .

Because of her very busy schedule, she has been getting her education from home for years. She says that after she acquires her GED, there is a big possibility that she wouldn't go to college.

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

"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."

Cyrus recently bought a new mansion in Los Angeles worth $3.4 million.

Meanwhile, she is busy with her recently-released album "Can't Be Tamed".

"This album says the most about me," she said with pride.

"I wanted this record to be completely and totally honest. It's really about a little of everything going on in my life now."

Aside from promoting her new album, the Tennessee-born teen star is currently working on a new film and has no plans of retiring anytime soon. Cyrus has previously stated that she intends to focus more on acting rather than singing in the future.
