This weekend, he was photographed in Italy on a boat with James Corden and Victoria's Secret model Jacquelyn Jablonski — as one does!
Although the image is a tad blurry here, some fans noticed that the singer appeared to be sporting the name "Olivia" on his thigh:
Of course, when it comes to deducing the tattoo's inspiration, one's mind might wander to Harry's ex Olivia Wilde. After all, the two were reportedly together for almost two years, during which time they did go on vacation.
There is also a 2015 One Direction love song called "Olivia," which includes lyrics like, "I live for you, I long for you, Olivia."
For what it's worth, Harry does have tattoos that are tributes to other people. He has his parents' birth years inked onto his shoulders and his grandmother's name on his arm. There are also plenty of unknowns, like the names "Arlo" and "Jackson."
It's not super clear when Harry got this particular "Olivia" tattoo — and I suspect we won't have much more clarity anytime soon.
