text: The couple were married in a civil ceremony in the Hall of State of the Royal Palace of Stockholm on  25 May 1961. The bride's grandfather, King Gustaf VI Adolf, hoped for a Lutheran ceremony, but Pope John XXIII forbade this. The bridesmaids were the bride’s sister Princess Christina and cousin Princess Benedikte of Denmark; the groomsmen were the bride's brother Crown Prince Carl Gustaf and her cousin Count Michael Bernadotte of Wisborg (son of Sigvard Bernadotte). That evening, the King held a ball at the Royal Palace. A Roman Catholic ceremony was held at Sankt Johann Church at the groom's family seat of Sigmaringen, Germany, on 30 May 1961. Birgitta applied to convert to Roman Catholicism when she married the Hohenzollern prince, but her application was rejected in wording which questioned her spiritual commitment to the change.
  Prince Johann Georg and Princess Birgitta separated in 1990, although they remained married. She lives on the island of Mallorca in Spain, while her husband lived in Munich. He died in 2016.
