Inés Zorreguieta was found dead in her apartment in Buenos Aires yesterday night.
Zorreguieta and the Queen had a close relationship, as Zorreguieta was a bridesmaid at her older sister's 2002 wedding to then Dutch Crown Prince Willem-Alexander. Reports of her receiving medical treatment for problems with her diet and depression began circulating when she returned to the country. Her death comes 10 months after the death of Maxima's father Jorge Zorreguieta, who died at the age of 89 from cancer.
