Millie Bobby Brown has a new name! In a recent Quiz On Me episode, VT gathered the cast of Stranger Things for their test on how well they all know each other! Millie was paired alongside her bestie Noah Schnapp for the interview, in which he was asked to guess the Enola Holmes star's real name. He said: "Millie Bonnie Brown." Which is correct! Kind of... Millie's birth name is Millie Bonnie Brown, unlike her professional name which features Bobby instead of Bonnie. But she recently changed it again! After marrying Jake Bongiovi, the actress revealed she took on her hubby's last name.
