A source has divulged that Tom Holland’s viral performance of “Umbrella” was the exact moment Zendaya became “smitten” with her now-husband.

The “Euphoria” actress was said to have fallen “hard for” Holland after witnessing his fishnet-clad, rain-soaked 2017 drag performance of Rihanna’s “Umbrella” during an episode of “Lip Sync Battle,” according to a source for the Mail on Sunday.

The insider reportedly told the newspaper that the daring performance — complete with fireworks — “sealed the deal” for the “Greatest Showman” star, 29.

“It’s not just sexy but it shows how amazingly talented he is,” the source told the outlet. “It takes a lot of confidence for a straight guy to pull off drag.”

During the performance — which has since gone viral — the “Dune” actress could be seen gaping and laughing in disbelief as Holland performed sultry choreography in black frilly shorts and a latex corset top.

“When he was announced as Spider–Man, people were taken aback because he’s slightly wimpy,” the source told the outlet. “But what he lacks in stature he more than makes up for in talent.”

They added of the famous moment, “You can see the shock on her face but then the admiration. I’m sure it’s something they will show their kids one day.”

Reps for Zendaya and Holland did not immediately respond to Page Six’s requests for comment on Saturday.

The report emerged just days after the “Spider Man: Far From Home” actor, 30, confirmed he and Zendaya are husband and wife after months of speculation.

During an interview with Esquire published Tuesday, the “Avengers: Endgame” actor was asked if he had to clarify to family that AI photos of them at a wedding celebration were bogus.

“No, because they were all there,” Holland said, adding, “That’s all you’ll get on that.”

Holland made no secret of the fact that marriage to the Emmy winner has been good to him.

“She’s my best friend, and I’m the happiest I have ever been when I’m with her,” he told the outlet. “But I have also never felt so supported and safe, ever. Period.”

The power couple was first romantically linked back in 2017 amid filming of “Spider-Man: Homecoming,” though they didn’t go public until years later, in 2021.

In February, Zendaya set the rumor mill on fire by wearing a simple gold band instead of her multi-carat engagement ring during an outing in Beverly Hills.

Her stylist Law Roach, subsequently told “Access Hollywood” at the SAG Actor Awards in March that “The wedding has already happened,” adding, “You missed it. It’s very true.”
