In late 2009, Montag had 10 procedures done in a single day, including breast augmentation, neck liposuction, and a chin reduction, People reported at the time.
People estimated that the operations cost upwards of $30,000.
Following the procedures, the reality TV star told the magazine said she'd never felt more beautiful and sexier. I didn't know I could have this much confidence.
Years later, however, she expressed different sentiments about the work she had done.
I was way too young to make such a life-changing decision, Montag told Cosmopolitan in a recent interview. She said she was under so much pressure because it was the beginning of comment sections and negativity and hate on the internet.
