The couple were photographed kissing while out in Los Angeles earlier this year.
Tom Holland is showering Zendaya with love on her special day! On Wednesday, the 25-year-old actor took to Instagram to share a sweet tribute to his Spider-Man co-star and rumored girlfriend on her 25th birthday.
Posting an adorable behind-the-scenes photo of the pair taken by the Euphoria star herself, Holland wrote, "My MJ, have the happiest of birthdays. Gimme a call when your [sic] up xxx."
In the snapshot, the actors are seen posing for a mirror selfie while on the set of a Spider-Man movie. Holland wears his superhero suit with his face covered in fake bruises and cuts while Zendaya stands behind him with a big smile, resting her face on his shoulders as she takes the photo with a vintage camera.
The birthday girl took to the comments section to respond to the post, writing, "Calling now ♥️."
Although relationship rumors between Holland and Zendaya have been circulating on-and-off since 2017, the couple seemingly confirmed they are an item after they were spotted making out in a car in July.
The Spider-Man: No Way Home co-stars have yet to publicly address the romance speculation, but they were recently photographed getting cozy at a wedding. In a snapshot posted by their friend Esteban Camarillo to his Instagram Stories last month, Zendaya smiled and leaned her head against Holland as he held on to the sleeve of her dress.
Back in 2019, the Devil All The Time alum was romantically linked to Olivia Bolton. Meanwhile, Zendaya was spotted getting close with her Euphoria castmate Jacob Elordi, who previously dated Joey King.
The rumored couple are set to appear together in the upcoming third installment of the Spider-Man franchise. Watch the trailer here!
