Millie Bobby Brown has officially adopted her husband's last name, becoming Millie Bobby Brown Bongiovi, after their secret wedding in May. She revealed this milestone on Instagram while sharing behind-the-scenes photos from the set of Stranger Things 5, captioned '11 in 5.' Fans reacted positively, expressing excitement over her new name, which was prominently displayed on a blackboard in her post. Brown's marriage to Jake Bongiovi, son of rock legend Jon Bon Jovi, was confirmed by Bongiovi in a recent interview where he described the ceremony as small and family-oriented. The couple, who began dating in June 2021 after meeting on Instagram, is reportedly planning a larger celebration later this year. As they prepare for the final season of Stranger Things, anticipation builds among fans for both the show and the couple's future events.
