Princess Alexandra was christened on 19 September 1999, in a ceremony at her father's hunting lodge Auerbach, near Grünau im Almtal, Upper Austria.
The princess's godparents are:
- Alexandra, Princess of Leiningen (paternal aunt)

Per Hanoverian family tradition, she was named for her six godmothers:

A German-British-Monacan (German/British from her father, Monégasque from her mother. She is referred to as Monacan because she was born outside Monaco to a Monégasque parent) Princess by birth, she grew up in France, about 40km outside Paris. She began attending school in the Le Mée-sur-Seine, France area, before moving back to Monaco with her mother in 2009. In the autumn of 2009, she began attending L'Institut François d’Assise Nicolas Barré, a private Catholic school in Monaco. She recently should have finished 1e (equal to the 11th grade in the US System) this year, and should be beginning T (equal to the 12th grade in the US System) this fall.
Being royal and holding multi-princess-ships, the young princess speaks several languages fluently, and is likely in the process of learning more. She is fluent in English, French & German, and could possibly be learning Spanish, Italian, and Monaco's local dialect, lang Monégasque in school. It is said that she speaks English with her father and German-born elder half-brothers, German with her nanny, and French with everyone else.
Until the births of Prince Jacques & Princess Gabriella of Monaco, she was the only grandchild of Prince Rainier III to hold any sort of title, even if her title isn't Monégasque. With the birth of the twins in December 2014, she is in 7th place for the throne of Monaco.
She has a close friend, who is also her second cousin (Princess Caroline is cousins with the girl's namesake and grandmother), Christine Knecht de Massy. The pair can often be seen paling with one another at events involving the whole family, whether it be reading at her uncle's wedding (Christine is the redhead in Green), and attending the 2011 Monaco Global Champions Tour (Princess Alexandra has her back to the camera, with the ponytail). In 2015 so far, she attended the presentation of her little cousins to the public, her little cousin's baptism, the LGCT Monaco,
The dynamic duo can also be seen promoting their school's (Christine is said to be a year behind Princess Alexandra at L'FANB until she moved to South Africa a few years ago) mathematics and science programs throughout the school and local community.
She is presently 5th in line for the Monégasque throne, after her sister Charlotte. Since she was not raised Catholic, she is 400+ in line for the throne of Great Britain after her two eldest brothers. She is the greatx6 granddaughter of King George III, through King George III's son, Prince Ernest August I of Hanover. In her lineage, she is somehow related to nearly every current reigning monarch.

In recent years, Princess Alexandra has taken to social media-albeit more quietly and discreetly than her Ducuruet cousins. The only one I am 100% aware that she has is instagram (DO NOT ask for her link, my response is NO, even if her account is private), but she likely has other accounts as well.
