"I would say that none of those people know me at all," said Montag. "And that's just a judgment. I'm not addicted."
"The Hills" star said she had surgeries done three years ago as well, but that the intervening procedure-free time proved she was not addicted.
"If you're addicted to something, you have to do it all the time, not once every couple years, if even," she said.
If she's not addicted, she's admittedly obsessed.
"Before I went into my surgery, I was obsessed because I had to look through hours of photos of which boob size I wanted in 'Playboy,'" she said. "I did do that. I did for hours, and looking at which size, and how it looked, and what it would like on my body...You have to be prepared for your surgery. So if you're going to do surgery, it's like doing research, you know, for a paper that you're writing. You really want...to show the doctor the photo so there's no misconceptions, because I don't want to go in again."
But why go in at all? Montag says one reason is that she was teased about her looks as a child. But she also wants to become a pop star.
She told People magazine that she's entering the world of music and that she feels like she's competing with the likes of Britney Spears.
"I am trying to be a pop star, and I just have my album that came out," said Montag. "And, you know, it's a very cutthroat industry. And it's a very cutthroat business. And when Britney was in her prime, it was her sex appeal that sold. And without that sex appeal, I don't know if she would have had the career she would have had."
Montag's surgeon, Dr. Frank Ryan, defends his patient's decision, saying its not uncommon in Hollywood.
"We're getting literally hundreds of calls from patients who want the Heidi Montag bombshell," he said.
But why so much plastic surgery?
"I disagree that it is that much plastic surgery," said Ryan. "These are little tweaks and things we did ... these were all kind of small things. ..."
Montag said she liked the change. "I see ... improvement," she said. "I think that it sounds crazier than it looks."
