Former Miss Argentina lost her life after going under the knife to get firmer buttocks.
Solange Magnano, 38, who was crowned Miss Argentina in 1994, died of pulmonary embolism after undergoing a gluteoplasty in Buenos Aires.
It is normally routine procedure, which involves placing implants in the buttocks to give them a firmer outline.
According to Roberto Piazza, a close friend, the procedure involved injections and the liquid "went to her lungs and brain."
"This woman who had everything is dead because she wanted to have a slightly firmer behind," The Times quoted Piazza, as saying.
Magnano underwent the cosmetic surgery on Nov 26, but was rushed to hospital next day due to an acute respiratory deficiency.
After three days in critical condition, she suffered the embolism and died.
"She only underwent the procedure because she thought it was no big deal," said Guillermo Azar, another close friend of Magnano's.
Juan Carlos Seiler, former president of the Buenos Aires Association of plastic surgeons, suggested the doctor who performed the procedure might not have been "a real professional from an approved" cosmetic surgery centre.
