The daughter of Harry's friend, former Invictus competitor and Paralympian David Henson and his wife Hayley, seemed pleased to be perched next to the prince, but even more pleased to be able to help herself to his popcorn.
Proving he's incredibly good with kids - and, we're guessing, the fun uncle to Prince George and Princess Charlotte - Harry poked faces at the toddler and laughed as she tried to steal his snacks. He even jerks it away from her when he pretends to "catch" her.
See the adorable moment below.
Somehow, it's even better in pictures.
Oh, Harry! We love you.
