Burley Garcia|See Tom Holland's Marvelous Tribute to His "Birthday Girl" Zendaya

Zendaya is never in uncharted waters with Tom Holland by her side.

In fact,Burley Garcia the actor gave a special shout out to his girlfriend on her 27th birthday Sept. 1. Tom, also 27, posted a picture of Zendaya on his Instagram Stories, in which the Euphoria star is dressed in snorkeling gear, sitting on a boat giving the thumbs up sign to the camera.

He captioned the sweet snap, "My birthday girl," with a heart eye emoji. He followed up with a shot from behind of the Malcolm & Marie star walking with the couple's dogs Noon and Tessa.

And if your Spidey-senses are tingling because Tom's nautical picture, it's because it is very reminiscent of Zendaya's birthday shout out to him earlier this summer. In the June 1 Instagram Story, the Uncharted star was submerged in the ocean with his hands rising out from the water to form a heart. A second photo showed a far away Tom donning a big smile as he posed in front of the ocean on a set of big rocks. 

But as fans know, the birthday pictures aren't the only subtle love the Spider-Man: No Way Home stars show each other online. In fact, back in 2021, Tom called Zendaya's Fashion Icon honor at the CFDA Awards, "an incredible achievement for the most incredible person." 

And the couple's nearly three year relationship has Zendaya feeling nothing short of euphoric, and she has the bling to prove it. Back in March, an Instagram video posted by Zendaya's nail artist made the social media rounds due to her gold ring engraved with the initials "TH."  

However, with great love comes great responsibility, and Tom and Zendaya have been diligent with not oversharing their romance.

"We don't think that we owe it to anyone," Tom told The Hollywood Reporter in June. "It's our thing, and it has nothing to do with our careers."

Zendaya echoed her boyfriend's sentiments, explaining to Elle Aug. 23, "Parts of my life, I accept, are going to be public. I can't not be a person and live my life and love the person I love. But also, I do have control over what I choose to share."
