Demi Lovato is out of rehab and doing better than ever.

The pop star took to Twitter for the first time in weeks to address rumors surrounding her sobriety. In a multi-part message, Lovato urged fans not to "believe what you read," adding that "People will literally make up stuff to sell a story." The 26-year-old added that if she feels "like the world needs to know something, I will tell them MYSELF."

"Otherwise people stop writing about my recovery, because it's no one's business but mine. I am sober and grateful to be alive and taking care of ME," Lovato tweeted.

"Someday I'll tell the world what exactly happened, why it happened, and what my life is like today.. but until I"m ready to share that with people please stop prying and making up s--- that you know nothing about. I still need space and time to heal.."

Lovato continued, "Any 'source' out there that is willing to talk and sell stories to blogs and tabloids about my life isn't actually a part of my life because most of the s--- I see is soooooo inaccurate. So newsflash: your 'sources' are wrong."

The "Sober" singer said she "would love to set the record straight on all the rumors out there," but didn't feel she owed it to anyone to do so. Lovato said her true fans know how hard she's working on herself, and she didn't feel the need to prove it.

"I'm happy and clean and I'm SO grateful for their support," she said.

Lovato added, "I'm so blessed I get to take this time to be with family, relax, work on my mind, body and soul and come back when I'm ready. I have my fans to thank for that. I'm so grateful, truly. I love you guys so f---ing much. thank you."

The musician was rushed to the hospital in July for an apparent drug overdose. She has since completed treatment.
