It’s clear that whatever Mendes chooses to ink for life, he always picks something extremely personal and meaningful.

Prior to inking his sister Aaliyah’s full name, Mendes enlisted Navasard to tattoo the letter “A” behind his ear. This particular trip to the tattoo shop was extra special, as Shawn accompanied girlfriend Camila Cabello as she got her first-ever tattoo — a quote from 1998’s “Shakespeare in Love” on her pinky — during the same session.

The Canadian artist got his first tattoo in 2016 from artist Livia Tsang. The tree-filled guitar’s meaning is more complicated than meets the eye; the instrument’s neck represents the skyline of Mendes’ native Toronto, including the famous CN Tower, and includes a sound wave of his parents and sister saying, “I love you.” The body of the guitar is made up of trees and their reflection in water.
