"Okay, are you ready?" I say through the door to Olivia's room as I wait for your signal to enter.

I just got my first haircut in five years. My long hair is gone now; I'm back to short-haired Harry. The fans are devastated, but you're so happy. You've always been urging me to cut my hair, and now that I'm about to start filming "Dunkirk," it was the perfect excuse.

Although we're both a little scared about our two-year-old daughter's reaction. She's always seen and known me with long hair, and she might not recognize me at first. Besides, Olivia is always full of surprises, so you never know how she'll react.

I open the door after hearing your "come in," and my gaze lands directly on Liv in your arms, who looks at me with a small frown. She thinks I'm a stranger, cool.

I slowly approach you with a smile and open my arms slightly. "Hi baby, it's daddy. Do you want to come with me?" I say, making a move to pick her up, but she cries instantly and grabs onto your neck. "Oh my God, this was a terrible idea! She doesn't know who I am!" I panic instantly.
