Don't think so.
The last information was from October 4th, that she was due for the end of October. The birth could be easily take place between the end of October/beginning of November.
Okay...all those publications state that the little boy was born late last night/early this morning....at the Princess Grace Maternity-in Monaco.
I bet Dimitri is ecstatic that he has a son. Will they name him Jean-Pierre?
Congratulations to the family if the baby is already born!!! But... why name him Jean-Pierre???
Jean-Pierre Rassam is Dimitri's late father. "Jean" and "Pierre" are also Grimaldi names.
I am hoping that he will be called "Charles" which is not only a Princely Grimaldi
name, but a derivative of both Caroline and Carole.
Also "Julien" is nice and is the name of one of Dimitri's cousins who died young.
ETA: Several posters have wondered if Charlotte and Dimitri knew each other as children. According to the article below, they have known one another for years and had a "remote friendship" before being re-introduced by friends in Paris in December 2016.

Hmmm....not sure about "Balthazar"...is it part of the Grimaldi, Casiraghi, or Rassam family tree?
One thing I can safely tell you about the little one, sight unseen...I am certain he has a GREAT head of hair if he takes anything like mummy and papa!
