Jennifer Pamplona, 24, from Sao Paulo, Brazil, said she was altering her body in memory of her late boyfriend, who dreamed of her becoming a human doll.
The TV presenter has undergone nearly a dozen procedures, including nine within 24 hours, and looks so dramatically different her own mother didn't recognise her.
She is already known in Brazil as 'Susi Doll' - a Barbie with more curves - but said her new aim is to have a larger bottom than Kim Kardashian's, despite doctors' warnings that her frame is not big enough.
'It was a way to love myself, it helped me so much in my personal life and career, it was the best decision I've made in my life.'
After his death from cancer in 2015, Miss Pamplona turned to surgery as a way to cope with her grief.
She said: 'When he died I was devastated, I never imagined something like that could happen while we were so young.
I was invited to change my body on a TV show shortly after he died and I chose to continue his dreams of turning me into a curvy Barbie doll for him.
'I found that plastic surgery took me out of depression, whenever I had something done I became so happy and everything became perfect.'
Miss Pamplona said she faced some backlash from members of the public and her own family.
She said:
'I looked so different after my surgeries, when my mother and grandmother saw me they didn't recognise me - it was really shocking for them but to me, I was perfect.Daily Mail.
