Update: Demi Lovato's aunt, Kerissa Dunn, posted to social media that her niece is "awake and responsive", according to TMZ.
Lovato was in the final days of her current U.S. tour.
Forbes also named her one of the Top 30 Under 30 in 2016.
Lovato has been open about her battle with addiction, and has sought treatment in the past. "Guess I always searched for what he found in drugs and alcohol because it fulfilled him and he chose that over a family", she said.
The two rose to fame alongside one another on Disney's Camp Rock, and patched up a short blip in their friendship to become extremely close over the years.
But a month ago, she released a song entitled "Sober", in which she appeared to indicate a relapse, opening with the line, "I got no excuses for all these goodbyes".
She has been politically outspoken, pressing for gay equality and putting on a passionate performance of "Skyscraper" - another song that deals with her past self-harm - for this year's youth-led March for Our Lives in Washington in support of gun control. In a statement, they said, "In light of recent reports, we have chose to replace the episode of BEAT SHAZAM with another all-new episode".
Lovato was scheduled to perform in Atlantic City on Thursday and in Toronto on Sunday.
Fans of the singer were shocked after she revealed she had relapsed with new single, "Sober", released in June. I am so happy you're alive. "She is a light in this world, and I am sending my love to her and her family", DeGeneres tweeted.
