A former beauty queen has died of complications after botched cosmetic surgery on her buttocks.

Former Miss Argentina 1994 Solange Magnano, 38, passed away in Buenos Aires Sunday after falling deathly ill with a pulmonary embolism following gluteoplasty surgery earlier in the week.

The normally routine procedure –which involves placing implants in the buttocks to give them a firmer outline — turned deadly for the mother of eight-year-old twins, who suffered a blocked lung artery during three days in intensive care.

Her close friend and fashion designer Roberto Piazza said the brunette had become fixated with her looks as her once thriving modeling career approached its end. Magnano ran her own modeling agency in Argentina, but still didn’t feel fulfilled, says Piazza.

“Solange was a girl who had everything. She lived the life of a goddess, she was the envy of everybody,” he said. “Now she is dead because she wanted a slightly firmer behind. She died because of her obsession with beauty.”
