InstagramThe secret's out: The Pretty Little Liars cast got matching tattoos!
Lucy Hale Instagrammed a photo with Ashley Benson, Troian Bellisario, Shay Mitchell, Sasha Pieterse and Janel Parrish and their matching index finger tattoos.
"This happened," she wrote. "Thank you @shamrocksocialclub for taking care of us. We couldn't not get tattoos to commemorate the show! And obviously on our 'shh' finger."
This sentimental ink, while special, isn't exactly unique. Just a few weeks ago, actually, Orlando Bloom shared a #TBT from 2001 when he and the rest of the Lord of the Rings cast got matching tattoos ("Nine" in elvish) to commemorate their experience filming.
Art inspired by J.R.R. Tolkien has already proven it stands the test of time; the same can't necessarily be said for late '90s boy bands. 98 Degrees members Jeff Timmons and Nick Lachey both inked their band name on their biceps at the height of their fame. Jeff still has his 98 Degrees ink, but Nick filled his in.
"It was just time to color it in," he told AOL back in 2014. "I colored it in actually while we were still a group, still touring. It wasn't like I was saying, 'Oh, that chapter's done. Time to move on.'"
Adam Levine and Jesse Carmichael both got the Roman Numeral X tattooed on their arms to commemorate 10 years of Maroon 5.
Let's not forget about the cast of Suicide Squad—or as Margot Robbie might spell it, SKWAD.

The actress gave Jared Leto and Will Smith matching tattoos as a way of getting them in character.
There was even a time, way back in 2012, that One Direction was still a fivesome and Louis Tomlinson, Harry Styles, Liam Payne and yes, Zayn Malik each got matching tattoos.
They didn't say 1D, or anything already regrettable. This was just a little ankle ink between bros.

And even though the Jonas Brothers disbanded years ago, Joe Jonas and Nick Jonas are forever bonded by the matching tattoos they got ahead of the 2016 MTV VMAs.
And then there are the Olympians who, understandably, want a permanent reminder of their athletic glory.
Swimmer Missy Franklin got the Olympic rings inked back in 2012. "Can't believe it!" she tweeted at the time. "My one and only!"
