Famous Spider-Man: No Way Home star Tom Holland is pretty well known for giving spoilers of his on-screen endeavors. However this week, he revealed a spoiler of his off-screen life on Instagram when he wished his co-star Zendaya a happy birthday.

He posted to Instagram yesterday a photo of Zendaya embracing Holland in his movie makeup and taking a mirror selfie on the set of Spider-Man.

The caption read:

"My MJ, have the happiest of birthdays."

"Gimme a call when your up xxx."

Of course, everyone caught on when he called Zendaya "My MJ," implying they are not only an on-screen romance, but also in real life.

Zendaya commented in response:

"Calling now."

Capping it with a heart emoji.

The post has gotten quite a lot of traction, raking in over 17 million likes and 150 thousand comments.

The two actors were suspected of being a couple back in July when Page Six shared photos of the two leaning in for a kiss and then erupting into laughter.

But this wasn't the first time rumors had flown. Back in 2017, an anonymous insider spoke to E! about the two dating after getting to know one another during filming.

The insider said:

"They started seeing each other while they were filming 'Spider-Man'."

"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."

But in a short Twitter exchange, the rumors were shot down.

After years of wanting the rumors to be confirmed straight from the source, fans finally got that chance with Hollands Instagram post.

There's no shortage of celebration for the couple.

The newest film the two will star in is the upcoming Spider-Man: No Way Home, which comes to theaters December 17 this year.
