She is good friends with her elder second cousin once removed (I *think* that's right: Christine's great-grandmother is Princess Alexandra's great aunt, they share the same great-grandparents/great-great grandparents, Prince Pierre and Princess Charlotte), Princess Alexandra of Hanover. The pair can often be seen attending events together, like reading at Princess Alexandra's uncle's wedding (Christine is the redhead in Green), and attending the 2011 Monaco Global Champions Tour. She has also been spotted attending the International Circus Festival of Monte Carlo in recent years (2008 (redhead, center)). Because her father, she and her sisters *technically* lost their place in succession with the death of Prince Rainier in 2005, she and her family are known to keep out of the main limelight. Other than the occasional all family appearance or out and about with Princess Alexandra, she's kept away from the media's glare.
She attends the private catholic school, L'Institut François d’Assise Nicolas Barré, along with her younger sisters and second cousins once removed Princess Alexandra of Hanover and Camille Gottlieb. Along with Princess Alexandra, she is active in keeping a progressive program to promote maths and science in the school and community. She should presently be a year behind Princess Alexandra at the school.
It is presumed that she is named for her paternal grandmother, who died of leukemia before she was born.
