Millie Bobby Brown is in her momma era! Right after announcing she and hubby Jake Bongiovi adopted a baby girl this summer, the new parents stepped out in East Hampton, New York, for a walk with their daughter on Thursday. The baby was kept out of view in a stroller, but in pics obtained by DailyMail.com, it seems like the 21-year-old Stranger Things star may have hinted at her kiddo's name! She was spotted carrying a pink phone case with the letters "RWB" written in red at the bottom. "B," of course, seems to resemble both her parents' last names. But RW? Those must be the baby's initials.
