"It is very important for me to raise him knowing that he is beautiful and knowing that everyone is beautiful,' she said, adding, 'It's so messed up that I truly believe that except it doesn't pertain to me.
"I should not be a burden to my child. He shouldn't have to be supporting me. That's not his job."
She retreated from the public eye after the procedure designed to reduce fat cells had the opposite effect and bulges began to appear all over her body.
She said, "No one sees me", explaining that she has been in isolation and only leaving home to walk her dog or attend her son's school events.
Evangelista first opened up about her experience in September last year, sharing an emotional Instagram post about her cosmetic procedure.
"I told [Augie] he might be hearing some things, and he said he didn't care, that he's there for me," she said at the time.
Evangelista said she had undergone seven sessions of the fat freezing procedure from August 2015 to February 2016, and claims she was not warned of the side effects.
She is now taking legal action.
