Demi Lovato is resting up surrounded by her family after being rushed to hospital yesterday, her spokesperson has said in a statement.

The singer became unwell on Tuesday and police were later called to her Hollywood Hills home where she was reportedly found unconscious, and treated on the scene with naloxene.

It was first reported that Demi had overdosed on heroin, but that has now been contradicted.

Naloxene is an antidote to opioids, which includes painkillers.

Demi’s reported overdose comes as the US struggles with an opioid crisis, with 115 Americans dying from the drug on a daily basis.

However, a spokesperson for the star has said that some of the reporting surrounding Demi’s hospitalisation has been “incorrect”.

“Demi is awake and with her family who want to express thanks to everyone for the love, prayers and support,” the spokesperson told BBC News.

“Some of the information being reported is incorrect and they respectfully ask for privacy.”

Demi has been vocal about her battles with substance abuse over the years, and last month released new single Sober which revealed she had relapsed after six years of sobriety.

“Mommy, I’m so sorry I’m not sober anymore. And daddy please forgive me for the drinks spilled on the floor,” she sings on the track.

It finishes with: “I’m sorry that I’m here again, I promise I’ll get help/It wasn’t my intention, I’m sorry to myself.”

There was an outpouring of support for Demi on social media following the news of her hospitalisation, including well-wishes from the likes of Ariana Grande, Ellen DeGeneres and Lady Gaga.
