Many people observed that there was a noticeable height difference between Zendaya and Tom. It’s something that Holland is aware of and he occasionally makes self-deprecating comments about it. He wrote this message for Zendaya’s 21st birthday: “Thinking about how to get taller! Happy birthday mate. Miss you and I’ll have a drink for you.”
