"I hope I get my own Barbie one day," Montag said. But she said she doesn't feel like a Barbie.
"I think I just look like a different, improved version of myself," she said.
Montag said she wanted her admirers to know that beauty is on the inside but seemed to realize how her surgeries could undercut that message.
"I'm also in a different industry than they are," she said. "You know, I'm in a limelight. I'm in a different industry. And I have to do things that are going to make me happy at the end of the day. I'm living in my skin, and I look in the mirror and it's my career, my life.
"You only have one, so I want to take advantage of everything and be the best me in and out every way," she said. Montag is also embarking on a new career as a pop star. The title of her debut CD is "Superficial."
She said she's gone broke pouring her life savings into an independently produced music album.
