Ariel Winter is proud of her new ink.

The 18-year-old actress Instagrammed a meaningful tattoo of hers on Wednesday, which are the initials of her four nieces and one nephew displayed on her ribcage.

"My second and most special tattoo, the initials of five of the most important beings in my life: my nieces and nephew," Winter wrote. "Their initials are on my ribcage, on the side where my heart is. They are my inspiration, and my reason for living. Love these babies more than anything and proud to have their initials forever on my body."

The "Modern Family" star has an older brother and an older sister, Jimmy Workman and Shanelle Workman-Gray. In 2012, Shanelle was granted temporary custody before Winter was officially emancipated from their mother, alleging ongoing physical and emotional abuse. Winter is obviously close to her nieces and nephew -- Dakota Patrice Workman, Skylar Athena Gray, Parker Eleni Gray, Demetra Eleni Workman and Asher Ruben Gray -- as she continuously posts pictures of them on social media.

Earlier this month, Winter revealed she actually has three tattoos, when she showed off a script tattoo on her right thigh on Instagram.

"Peep tattoo 1 of 3. @_dr_woo_ is a master," she wrote, shouting out her tattoo artist.

Last month, Winter said she was in a "better, safer household" after her emancipation at age 17.

"It has been very sad for me, but at the same time it's been much better for me emotionally and physically to be on my own and have a better, safer household and support system," she told Ellen DeGeneres.

"She's been the best part of my life," she also gushed about her older sister. "She really is my best friend. She's the most important thing to me. She's been there for me through absolutely everything. And I just love her so much. I count on her more than anything."
