Meet eight-year-old Chloe: she’s about to have a brand-new baby brother, and she’s dying to learn what life will be like when he arrives. So she’s taking matters into her own hands and interviewing her favorite celebrity parents to get advice on how to be the bestest big sister.

For our third installment, Chloe interviews Rosie Huntington-Whiteley, actress, model, founder of much-loved beauty site Rose, Inc, and mother of two-year-old Jack. Rosie comes over for tea and gives Chloe advice on balancing sisterhood and third grade—and lets her in on the secret that baby wipes are going to be her new best friends.
