Tom Holland has seemingly finally gone "Instagram official" with girlfriend and Spider-Man co-star Zendaya with a sweet dedication for her birthday.
The couple have been connected on and off since 2017 but neither have publicly spoken about their relationship.
However, in honour of Zendaya's 25th birthday, Holland posted a sweet behind-the-scenes pic from filming, with Zendaya cuddling up to him from behind while he poses in his Spidey suit.
Alongside it, he wrote: "My MJ, have the happiest of birthdays. Gimme a call when [you're] up xxx"
MJ is Zendaya's character in the Marvel Cinematic Universe, and the love interest of Holland's Peter Parker.
While that could mean little more than a film reference on its own, the photograph comes weeks after the couple were snapped kissing in a parked car together in California.
Within three hours of the photo going up on Instagram, more than 10 million fans had liked it, with most believing it cemented the pair's relationship publicly for the first time.
It was further cemented by their co-stars sharing their own notes on the picture, with Marisa Tomei, who plays Peter's Aunt May in the films, posting a collection of rose emojis.
The cute couple's romance joins the previous Peter and MJ stars who have also found romance on set.
Kirsten Dunst dated Tobey Maguire while they filmed their Spider-Man trilogy, getting together during 2002's Spider-Man. However, they had split before the films' third instalment in 2007.
Andrew Garfield dated his Amazing Spider-Man love interest Emma Stone for five years from 2012 – although she portrayed Gwen Stacy, not MJ. They split in 2017.
In the new MCU, MJ is not short for Mary Jane, but instead has been given a revamp into Michelle Jones. Zendaya's dry-witted character prefers to be called MJ for short.
The latest Spider-Man film, titled No Way Home, is rumoured to see all three versions of Spider-Man collide as the Marvel series spins into the multiverse for the first time.
In the first trailer, the return of previous enemies including Alfred Molina's Doc Ock and Willem Dafoe's Green Goblin was confirmed.
The film hits cinemas in November.
