Look what I found!
Primeiro bisneto de Grace Kelly nasce em Londres com sangue brasileiro – Bruno Astuto – Época
It's a society column from Brazil saying that Grace Kelly's first great-grandson was born in London and that the palace is going to make an announcement very soon with the baby's name.
I noticed that he wrote 'grandSON' but sometimes in Brazil people use the male gender when they want it to be neutral. If that's true we'll really have to wait the palace's announcement
ps. i rarely post here, so i hope i'm posting on the right place.
