And while that isn't surprising - she is Zendaya - he is constantly making people fan themselves over how amazing he is to his co-star on social media.
After Zendaya rocked up to the Met Gala dressed like the hottest Joan of Arc you have ever seen, he posted this:
"All hail the queen. Killing it mate 🙌🏻," he wrote.
We all died.
However, it's not the first time he's completely fangirled over her online.
A Twitter user named Liv has pointed out this week that Tom ALWAYS comments on Zendaya's selfies. He complimented her "selfie game" with fire emojis on one pic, and commented "Yeasssss queen" on another.
WE NEED A TOM HOLLAND IN OUR LIVES.
It comes after we're all pretty certain that the two are dating.
Fans noticed that Tom stays over at Zendaya's house for days on end when he comes to L.A. from England. While he's there, the two also spend all their time together.
