21. Princess Ingrid Alexandra Of Norway
Princess Ingrid Alexandra of Norway is the eldest child of Crown Prince Haakon and Crown Princess Mette-Marit. She is currently second-in-line to inherit the throne — her grandfather, King Harald V, is the current ruler. Once Princess Ingrid Alexandra takes the throne, she will become the country's second female monarch, after the 15th-century Queen Margaret.
