Sharing a picture of the pair of them from behind the scenes shooting Spiderman, Tom wrote on Instagram: "My MJ, have the happiest of birthdays. Gimme a call when your up xxx."
Sorry... did he say "My" MJ? (Referring, of course, to Zendaya's Spiderman character, Mary Jane). Don't play with us, Tom.... That's so cute that we're even going to ignore the incorrect use of "you're" 🥰.
Zendaya soon replied to the tribute, commenting: "Calling now ♥️." Anyone know how to tap a phone line? Kidding, of course.
And yet... we still have so many questions about this relationship.
First of all, when did this happen? How did they go from pals to... maybe more than pals? And please can someone show us those pics one more time 😭.
When the initial snaps were published (view them here via Page Six), it was like someone had finally pulled the Spiderman mask from over our eyes and we could see the world clearly. The grass looked greener, the sun was rising and Tom Holland and Zendaya were kissing - five years after they first sparked dating rumours.
So what events led to this grand reveal? Take a look back through our timeline of the hookup of the century.
How did Zendaya and Tom Holland meet?
In 2016, Zendaya and Tom Holland were both confirmed to star in the new film Spiderman: Homecoming. Whispers of a romance were immediate.
The pair continuously popped up on each other's social feeds, spoke super highly of each other and, well, they simply just looked like a stunning new couple. No doubt.
Of course, one's imagination can run wild here. But when PEOPLE reported from a source that the couple were in fact a couple, a few things happened.
Firstly, the world combusted into fits of glee (well, those of us who were day one stans) with the source's insight on the sweet young couple.
"They've been super careful to keep it private and out of the public eye but they've gone on vacations with each other and try and spend as much time as possible with one another," the source told PEOPLE.
Secondly? Well, the pair completely denied the claims. Ah.
Zendaya referenced the article via Twitter, making light of the situation she and Tom clearly wanted to shut down.
"My favorite is when it says we go on vacations together HA! I haven't been on a vacation in years!😂😭🤣hbu @TomHolland1996 ???"
Tom meanwhile opened up about Zendaya in an interview, saying: "I'm a little worried [about dealing with fame … but] Zendaya is super famous and she's been through this and I just call her up and say, 'How do I manage being famous?' I'm very glad I have a friend like her."
Friend. Yes. Okay.
How long have Zendaya and Tom Holland actually been dating?
Zendaya and Tom's denial that they were dating in 2017 didn't stop the internet from basking in every single sign that proved these two had a good thing going.
In 2018, Zendaya literally slayed the Met Gala red carpet, and Tom was one of the first to call it out on Instagram: "All hail the queen. Killing it mate," he wrote next to a picture of Zendaya dressed as Joan of Arc on the infamous steps.
And then there was the other Instagram moment in 2019 where Tom posted a picture of himself, Zendaya and their Spiderman co-star Jacob Batalon.
In the cute pic, Zendaya stands with her arms around both men, but Tom appeared to tag her name over... well... his crotch.
Zendaya didn't miss a beat.
"I'm assuming because you don't know how to work ig, that's the reasoning behind my name placement," she cheekily teased in the comments.
Tom took it on the chin: "Thanks @zendaya for making me aware of my obvious blunder" he wrote, before fixing up the tag.
Fast forward through a pandemic, a Space Jam reboot and a rumoured fling with Jacob Elordi (more on that here), the year turned to 2021, and with it a shining beacon of hope in the form of pictures of Tom Holland and Zendaya making out in public.
Yes, last month the pair were seen macking on in Tom's luxe Audi while driving the streets of LA in July 2021. In the pics, Tom and Zendaya were playing about and looking at each other with that face. Hold us!
And if these new wedding photos are anything to go by, their relationship seems more than solid. Stay tuned guys - the first Instagram official picture could give Kimmy K an internet-breaking run for her money.
