Former Miss Argentina Solange Magnano died from complications after undergoing cosmetic surgery on her buttocks.

Magnano died of a pulmonary embolism Sunday after three days in critical condition following a gluteoplasty in Buenos Aires.

The operation went horribly wrong when and the liquids meant for her buttocks “went to her lungs and brain,” said Roberto Piazza, a close friend of the beauty queen.

“A woman who had everything lost her life to have a slightly firmer behind,” he said.
