This isn't the first time these cuties were seen together attempting to be ~inconspicuous~.
Our Spidey senses first began tingling when Zendaya and Jacob were sprung holidaying together in Greece by a tourist who accidentally snapped them in the back of his photo.
In the snapshot, the tourist (who had no idea he potentially just outed Jacob and Zendaya's secret romance) stands in front of the Acropolis in Athens. In the background - top right-hand corner - you can most definitely see Zendaya and Jacob walking amongst the tourists.
A big round of applause to our tourist friend Marcus for this incredible (and accidental) piece of juicy goss.
Adding weight to the romance rumours - and yes, they are just rumours at this point - was the fact Zendaya and Jacob were also snapped taking a photo with a fan while on their European holiday.
Whatever is happening between them, Jacob and Zendaya obviously want to keep it a fairly private matter for now.
When she was asked about her Grecian holiday, the Spider-Man star didn't give anything away, telling E!: "I went on vacation with my family, which was very sweet.
"It was kind of just my first time just chilling, you know, I haven't chilled in a really long time."
