Allman - who Cher, 79, shares with late musician Gregg Allman - was taken to A&E in Joshua Tree, California, after overdosing on Saturday morning, TMZ reported.

The 48-year-old is still in hospital “receiving the best care possible” and his “very lucky to have survived”. It is not known which drugs he took.

Grammy winner Cher’s “only concern right now is for her son's well-being, and she's doing everything she can to get him the help he needs,” sources said.

Allman, who is a singer himself, has spoken about his drug use before, previously revealing he started smoking weed and taking ecstasy when he was just 11.

Cher’s youngest child said his drug use led to some “close calls” with death, adding that he abused substances to “escape all the things in [his] past”.

“[Heroin] kind of saved me,” he told ET in 2014.

“If I didn’t have that at that point, I don’t know what I would have done … You may jump off a bridge. If you can only just go through that time period and live through it, and then get help.

“I did have some close calls and some moments of really feeling at the edge of mortality … I always kind of kept it a little bit safe, but you never can do that.”

The Believe singer claimed her son was “substantially unable to manage his own financial resources due to severe mental health and substance abuse issues”.

She feared that Allman was using regular payouts from a trust set up by his late father Greg - who died in 2017 - to buy drugs, according to court documents.

Cher's lawyers argued that the support Allman was getting was from people who tell him what he wants to hear and downplay the size of his problems.

They said his current apparent sobriety and mental health were illusory.

They said he suffers from bipolar disorder, has been recently homeless, and that having large amounts of money might lead to access to drugs that could endanger his life.

The musician said she was the best person to be his conservator, with two of Allman’s siblings also nominating her.

Cher also has a child, Chaz Bono, with her former husband Sonny Bono.
