Selena Gomez, who executive produced the Netflix series 13 Reasons Why, joined the show’s stars Alisha Boe (who plays Hannah’s ex-BFF Jessica) and Tommy Dorfman (who plays poet Ryan Shaver) for matching tattoos in Hollywood. The trio spent the afternoon getting inked with semicolons on their forearms, and they picked the punctuation mark for a very poignant reason.

The semicolon represents mental health awareness and suicide prevention. The 24-year-old singer/actress/executive producer shared videos and pictures on Instagram Live of the entire process.

Boe also shared the image on her Instagram account, and wrote in the caption, “I have received so much love and support from all of you who are watching 13 Reasons Why. 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. Those of you watching 13 Reasons Why and identify with Hannah Baker, please check out Beyond The Reasons on Netflix, or check out the link in my bio. Rest In Peace Amy Bluel [sic], who started this movement. Love you all (thx @ktal77 and @joymaryro for the inspo).”

Amy Bleuel, whom Boe references in her caption, was the mental health activist who started the mental health non-profit Project Semicolon. According to Bleuel’s interview with The Mighty, the inspiration behind the semicolon for a mental health organization is derived from its grammatical use. “In literature, an author uses a semicolon to not end a sentence but to continue on,” she said. “We see it as you are the author and your life is the sentence. You’re choosing to keep going.” Bleuel took her life on March 23, 2017, at the age of 31.

Gomez hasn’t been shy about what executive producing 13 Reasons Why has meant to her and how closely she relates to the project after publicly dealing with her own battle with depression. “I think the message, how I felt when I first read the book, I felt like Hannah, and now, seven years later, I still felt like Hannah even more than I ever did,” she told E! Online. “So I think the message and people, no matter what age you are, can relate to the story. Everybody has gone through this, and more than ever it should be talked about today.”
