On Friday July 5, Laeticia Hallyday celebrated the 89th birthday of her grandmother Elyette Boudou, nicknamed “Mamie Rock” in the presence of her two daughters Jade and Joy but also of Alcéa, the little-known little sister of Johnny's widow, aged only 16 years old.
Laeticia published a video of the event adding these few words:
A few days ago with our Queen ❤️ Elyette. Thank you for all the love and memories you give us. Happy birthday, my loving grandmother! 🌸 89 years old
On the video, we can see after a few seconds Alcea, the very young half-sister of Laeticia Hallyday, only 16 years old. In fact, his father André Boudou, divorced from his mother Françoise Thibaut (born Galtie) remarried Adeline Lanneluc-Sanson, a young woman from Béziers, with whom he had a daughter (Alcea) born in 2007.
