Demi Lovato posted a tribute to her friend Thomas on Wednesday (Oct. 9) after she said he died following a struggle with addiction.
"Devastated. Please hold your loved ones tight," she wrote to her Instagram Story. "Tell them they are special and that you love them. Make sure they know it. RIP to my boo."
She followed with a second post, adding, "Addiction is no joke.. heaven gained this beautiful angel last night because of that terrible disease. I'm crushed and will always miss you @sirtruss. If you or someone you know is struggling please know it's okay to ask for help."
