Millie Bobby Brown and Jake Bongiovi are getting swept up in wedding fever once again - though this time it wasn't their own! The newlyweds look loved-up in a sweet new picture that the Stranger Things actress shared via Instagram on Thursday, August 14, from her older sister Paige's wedding to fiancé Sam. In the snaps, Brown, 21, can be seen walking down the aisle in a gorgeous baby blue dress while holding a young boy, presumably a family member. In another pic, the supportive sister helps Paige navigate her way across grass while hoisting up the train of her dress.
