Demi Lovato is awake and recovering with her family after she was reportedly hospitalised for an overdose, her representative has said.

“Demi is awake and with her family who want to express thanks to everyone for the love, prayers and support,” Lovato’s representative said in a statement on Tuesday evening.

“Some of the information being reported is incorrect and they respectfully ask for privacy and not speculation as her health and recovery is the most important thing right now.”

The statement provided no details as to what led to the US pop singer’s hospitalisation.

According to reports by TMZ, the Mexico-born singer, who has spoken openly about her history of drug and alcohol abuse, overdosed on Tuesday morning at her home in Los Angeles.

The site said she was treated by Narcan, an emergency antidote for suspected opioid and drug overdoses.

The Los Angeles Police Department confirmed to The Independent they had received an emergency call for a 25-year-old woman who lives in Lovato’s area at 11.39am.

Lovato indicated in a new song released last month she had relapsed after six years of sobriety. On the song “Sober,” she sings the lyrics: “Momma, I’m so sorry I’m not sober anymore/And daddy please forgive me for the drinks spilled on the floor.”

In her YouTube documentary released last year called “Demi Lovato, Simply Complicated,” she says she first stated using cocaine when she was 17 and “loved it,” and openly discusses years of substance abuse, eating disorders and drinking.

She entered rehab at the age of 18, where she was diagnosed with bipolar disorder.

Lovato, who has some 69 million followers on Instagram, was in the midst of a US tour and was due to perform in Atlantic City, New Jersey, on Thursday.

The hashtag #PrayForDemi trended on Twitter and several celebrities posted supportive words, including Missy Elliott, Ariana Grande, Brad Paisley, Kesha, Bebe Rexha, Meghan Trainor, Maren Morris, Kehlani and British electronic group Clean Bandit, whose current single “Solo” features Lovato.

Ellen DeGeneres tweeted to say “it breaks my heart that she is going through this. She is a light in this world, and I am sending my love to her and her family.”

Lovato, who was a child actress on the TV series “Barney & Friends,” broke on the scene as a teen on the Disney Channel film “Camp Rock” and the network series “Sonny with a Chance.”

She went on to become a multi-platinum pop star, launching Top 10 hits like “Sorry Not Sorry,” “Skyscraper,” “Heart Attack.” Her 2015 album, “Confident,” earned her a Grammy nomination for best pop vocal album.
