Zendaya and Tom Holland's relationship has always had the makings of a classic Gen-Z friendship. With their casual Instagram posts and witty Twitter interactions, many fans still doubted it when they dispelled dating rumors in 2017.

But just this weekend, the two young actors shocked the Internet when they were spotted briefly kissing inside a parked car in Los Angeles.

The two have yet to confirm their status, but in the meantime, we take a look into their years-long friendship and how they got to where they are now.

2016—Spider-Man: Homecoming shooting

Before the release of the Marvel Cinematic Universe's (MCU) Spider-Man series, Tom and Zendaya were already hanging out and spending the summer together on and off shooting.

In July of 2016, Zendaya made her first appearance on Tom's Instagram through a polaroid summer photo with a friend.

2017 - First dating rumors

With the success of Spider-Man: Homecoming, the chemistry of Tom's Peter Parker and Zendaya's MJ couldn't be denied. Rumors soon started to spur of a romance between the two actors, with People first reporting that they started dating while filming Homecoming.

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," an insider shared with the site.

They're both really ambitious and they challenge each other but, most importantly, they make each other crack up. They seem to have a really similar sense of humor and love joking around together. They have great banter back and forth.

The pair were quick to dispel the rumors, which also alleged that they took a romantic getaway together after the film's release. Zendaya quipped on Twitter that she hasn't had a vacation in years, and tagged Tom in the post.

"Wait wait...my favorite is when it says we go on vacations together HA!"

“All hail the queen. Killing it mate ??.”
