Maxima has canceled all of her upcoming scheduled appearances and is believed to be making plans to travel from Holland to Buenos Aires.

Ineacutes was the godmother to Queen Maximarsquos youngest daughter, Princess Ariane, 11.

Queen Maxima, 47, married then Dutch Crown Prince Willem-Alexander in 2002 after meeting in Seville, Spain, in 1999 during the Seville Spring Fair. They have three daughters.

Maxima has said that she didnrsquot know her future husband was a royal when they met, and that he introduced himself as ldquoAlexander.rdquo Their relationship initially resulted in controversy due to the fact that Maximarsquos father, Jorge Horacio Zorreguieta, was a controversial figure, who at one point even threatened Maximarsquos marriage to Willem-Alexander.

Zorreguieta served as the Secretary of Agriculture the during the dictatorship of President Jorge Rafael Videla (who is now not recognized as a legitimate president by the Argentinian government), as well as the beginnings of the Dirty War, a military regime that saw the disappearance and murder of thousands of Argentinians, according to the New York Times.

Zorreguieta resigned before the end of Videlarsquos presidency argued that he wasnrsquot aware of the Dirty War, as he was a civilian during the majority of it. However, public outcry was so strong in the Netherlands that the Dutch Parliament asked an outside expert, Professor Michael Baud to look into the matter. Baud announced that Zorreguietarsquos ignorance of the crimes would have been unlikely. The marriage was still approved by Parliament, because Maxima herself was not involved, but Zorreguieta was not permitted to attend their wedding, according to Dutch News. Her mother also did not attend the nuptials, out of respect for her husband.
