The regal couple — who married in a lavish royal wedding in June 2015 — announced they are set to welcome their first baby last October with an official statement released by the Swedish Royal Court. “We are so happy and excited to announce that we are expecting our first child. We are very much looking forward to it,” the duo said of Sofia’s pregnancy.

The newborn baby will be the fifth in line to the Swedish throne. Carl Philip’s older sister, Victoria, Crown Princess of Sweden, 38 — who is also expecting — is currently the heir apparent and will ascend to the throne when their father, King Carl XVI Gustaf, 69, either passes away or abdicates his title.
