The former Hills star admitted that she would not repeat the experience and insisted that she is a much different person than she was when she went under the knife in 2009.
"I wouldn't do it again, that's for sure. It was a lot more than I could have expected," the 25-year-old explained to Celebuzz.
"I really hate talking about it now because it was so long ago. I was a much different person back then to who I am now. I didn't realise how much of The Hills - and going through that - would define who I am."
She added: "I'm really looking forward to the next phase in my life. I know I'll never be able to get away from a lot of it, but I won't give up trying to prove I'm more than just that."
Montag recently confessed that undergoing liposuction is her biggest regret as she got cellulite after the procedure.
