Selena Gomez and '13 Reasons Why' Cast Members Get Meaningful Matching Tattoos -- See Their New Ink!

The Netflix series deals with a heavy subject.

Selena Gomez's new tattoo is all about continuation.

The 13 Reasons Why executive producer and two of the Netflix series' cast members shared photos of their matching semi-colon wrist tattoos on Sunday, along with messages for what the ink means to them.

"I have received so much love and support from all of you who are watching 13 Reasons Why," wrote actress Alisha Boe. "Today- Tommy, Selena and I got tattoos of a semicolon. Project semicolon is a movement dedicated to presenting hope for those suffering from depression, thoughts of suicide, addiction, and self-injury."

"Rest In Peace Amy Bluel, who started this movement," she continued. "Love you all."

The series deals with depression and suicide, and co-star Tommy Dorfman shared his own struggles with the disorder on Instagram.

"Today was a magical day. Another day to be grateful to be alive. Alisha, Selena, and I went together to get ; tattoos. The ; symbol stands for an end of one thought and a beginning of another," he wrote. "Instead of a period, authors use the semicolon to continue a sentence. For us, it means a beginning of another chapter in life, in lieu of ending your life."

"I struggled with addiction and depression issues through high school and early college," he added. "I reached out and asked for help. At the time, I thought my life was over, I thought I'd never live past the age of 21. Today I'm grateful to be alive, in this new chapter of life in recovery, standing with my colleagues and friends, making art that helps other people."

Gomez also posted about the tattoos, writing, "Wish the rest of the crew was with us today. Overwhelmed with the response and love @13reasonswhy is receiving. Thank you to each beautiful person who has watched and talked about the message of our show."

ET caught up with the cast at the March 30 premiere, where they opened up about working with Gomez.
