Shawn Mendes's little sister has his heart.

The pop star already has one tattoo to honor his 16-year-old sister, Aaliyah Mendes, and he's now added a second permanent tribute.
On Sunday, tattoo artist Kane Navasard posted a photo of Shawn's new tattoo: the name Aaliyah Maria in a cursive font. The tattoo appears on the singer's chest, just below his collarbone.
"A sweet dedication, on the man @shawnmendes," the tattoo artist wrote on Instagram, tagging the "In My Blood" singer in the photo, as well.
Shawn, 21, has not commented on the tattoo or given a reason for getting it. Last year, he also got the letter A tattooed behind his ear as a tribute to his teen sister.
The singer already has quite the collection of tattoos, including a sparrow on his right hand, a lightbulb full of flowers on his shoulder and a butterfly designed by a fan. He also has an elephant on his finger that he got with his mom. His most meaningful tattoo could be that of a guitar made of trees on his forearm. The very top of the guitar is reportedly a sound wave of his parents voices saying "I love you."
