Millie Bobby Brown and husband Jake Bongiovi's infant daughter just made her interview debut - sort of. Brown, 21, and her Stranger Things castmates teamed up for BuzzFeed's "The Kitten Interview" to play with rescue cats while discussing season 5 of the Netflix series. "That's my child," Brown quipped at the start of the Monday, November 17, YouTube video after her baby girl could be heard crying off-camera. "That's my kitten." Brown and Bongiovi, 23, announced in August that they welcomed their first child.
