In 2003, in France, Aleksandra met entrepreneur and investor Andrey Melnichenko. The couple married two years after their first meeting, in September 2005, and started to spend an international life between different continents and countries. Aleksandra and Andrey have since welcomed a daughter (2012) and a son (2017). Aleksandra and Andrey Melnichenko own two superyachts designed by Philippe Starck: Sailing Yacht A and Motor Yacht A which reportedly cost $500 million and $350 million to build, respectively, and are considered to be "one of the most advanced superyachts on the water" with "environmentally-friendly innovations."
