Passage: Brnabić was born in Belgrade. Her paternal grandfather Anton Brnabić (ethnic Croat), a Yugoslav military officer, was born in Stara Baška on Croatian island of Krk (present-day Republic of Croatia). He fought with the Yugoslav Partisans during World War II and was ranked lieutenant colonel (potpukovnik) after the war. Her paternal grandmother Mica was born in Gorobilje near Požega (in Serbia). Her maternal grandparents are from Babušnica, southeastern Serbia. Her father Zoran was born in Užice in 1950 and finished his studies in Belgrade, where the family lived.Brnabić is a lesbian, and lists as the fifth openly LGBT head of government in the world following Jóhanna Sigurðardóttir, Prime Minister of Iceland from 2009-13, Elio Di Rupo, Prime Minister of Belgium from 2011-14, Xavier Bettel, Prime Minister of Luxembourg since 2013, Leo Varadkar, Taoiseach of Ireland since 2017, and the second female LGBT head of government overall following Jóhanna Sigurðardóttir. In 2017, she became the first head of government of any Balkan country to attend a gay pride march when she attended one in Belgrade. In 2019 her partner Milica Đurđić gave birth to a boy; Brnabić is therefore believed to be the first prime minister in a same-sex couple whose partner gave birth while the prime minister was in office.
