The reality is that besides Pierre and Louis (no kids yet and married), there is no one in this family who can cast stones about children at least conceived out of wedlock. None.
-Caroline was at least three months pregnant for 2 out of 3 weddings. She married Stefan December 29, 1983 and had Andrea June 8 1984. She married Ernst January 23 1999 and had Alexandra July 20 1999.
-Stephanie married Daniel Ducruet July 1, 1995. Louis was born November 26, 1992 and Pauline was born May 4, 1994 (so they were over 2 1/2 years old and almost 14 months old when their parents married). She never married Camille's father (in fact never included his name on the birth certificate even) though he was identified later as Jean Raymond Gotlieb.
This generation:
-Andrea and Tatiana had Sasha March 21 and married August 31 in 2013
-Charlotte never married Raphael's father. Balthazar was born October 23, 2018 and she married Dmitri June 1, 2019 (over 7 months old)
The tension of Jazmin with her Aunt Caroline or stepmother seem to be rumors at best. I have never seen or heard any clear proof of problems with either women. Jazmin was 19 when Charlene and her father married, she was 14 when they officially started dating in 2006.
Albert and Charlene met in 2000, so before Alexandre was born, but they weren't officially together until he was 3 years old. So I doubt even he caused any issues with the couple.
There were stories at the time of their wedding that Charlene had tried to flee (total rumors) as some third love child had arose. Total rumors.
