The Kick-Ass star, 19, lost her gran in 2014, and, while in New York City to promote her new movie Neighbors 2: Sorority Rising on Monday (23May16), she decided to make a stop at Manhattan's West 4 Tattoo parlour to add to her body of art.

Tattoo artist Jon Boy has since shared a series of photos of Chloe's visit on, revealing her grandma's name, Janette Duke, written in a script font above an existing flower tattoo on her left ribcage.

The professional simply captioned the image, "JanetteDuke #jonboytattoo".

Chloe also decided to get a small, matching tattoo with her friend, actress/singer Kathryn Gallagher, with their initials "CK" etched in white ink on their ankles.

After the session, Jon Boy let the teenager take charge of the tattoo gun to make her mark on his forearm.

"Pro @chloegmoretz #jonboytattoo," he wrote beside a brief clip of Chloe in action.

The actress isn't Jon Boy's only celebrity client. Earlier this month (May16), he helped to add to Justin Bieber's tattoo collection, after inking a tiny cross under his left eye, and subsequently revealed the discreet design, similar to one Jon Boy has himself, was a nod to his faith in God.

"We were sitting there and chatting about why we wanted it near the eye, and it's really to see people through the cross - to see people with our eyes through the cross with our grace and with our love," the tattoo artist told The Hollywood Reporter.

Jon Boy also counts the likes of models Kendall Jenner and Hailey Baldwin as clients.
