Her post was met with encouragement from celebrities and fans alike.

“I’ve missed you so very much,” singer Christina Aguilera commented on the post. “And we keep on tickin – till the end of time – I looooove youuuuu! Can’t wait to continue to have you by side now.”

Lovato's post referenced her blue belt in Brazilian Jiu Jitsu, which she earned in August 2017.

She has opened up about her battle with addiction since the suspected overdose in July.

\"I have always been transparent about my journey with addiction,\" she wrote on Instagram in August. \"What I've learned is that this illness is not something that disappears or fades with time. It is something I must continue to overcome and have not done yet.\"

\"I now need time to heal and focus on my sobriety and road to recovery,\" she added. \"The love you have all shown me will never be forgotten and I look forward to the day where I can say I came out the other side. I will keep fighting.\"

The post has since been deleted.
