Demi Lovato is mourning the loss of a friend who died following a battle with addiction.
The "Sober" singer shared the sad news to fans by posting a tribute on Wednesday.
Sharing two separate posts, Demi stated she was "devastated" and told fans to "please hold your loved ones tight."
She continued, "Tell them they are special and that you love them. Make sure they know it."
Tagging her friend, whose name is Thomas, she also posted another photo revealing he lost his battle with addiction.
"Addiction is NO joke.." she wrote. "Heaven gained this beautiful angel last night because of that terrible disease."
Demi added, "I'm crushed and will always miss you."
She ended her tribute by encouraging those who need help to seek it.
Demi has struggled with her own addiction issues in the past.
Most recently in 2018, when she landed in the hospital following a near-fatal overdose in her Hollywood Hills home.
As The Blast first reported, Lovato was uncooperative with police and would not tell responders what drugs she took when she was questioned about her overdose.
About two weeks later, she entered rehab where she stayed for three months.
Demi celebrated her one-year sobriety with a group of friends this past July.
Since leaving rehab, Lovato has been dedicated to her sobriety and health. She has returned to the studio and has signed with Justin Bieber's manager, Scooter Braun.
In March, Lovato reflected on what would have been seven years sober.
"Today I would've been 7 years sober," the singer wrote. "I don't regret going out because I needed to make those mistakes but I must never forget that's exactly what they were: mistakes."
