Demi Lovato met her personal development coach after "a bad mushroom trip".

The 24-year-old singer has suffered from depression, bulimia, and substance abuse in the past, and Mike Bayer - the mental health expert who helped her overcome her addictions - has revealed it was a particularly strong dose of the drug magic mushrooms that made the 'Confident' hitmaker want to turn her life around.

Speaking to ET Canada, he said: "We met after a bad mushroom trip. She asked for help and she had called her therapist and another person, both had said, 'Call Mike Bayer.'"

Now, the 'Cool for the Summer' musician can boast that she is in much better health, and has turned her efforts to helping others who suffer in the same ways she did. She now co-owns the CAST Centre in Los Angeles alongside Mike, and the pair work together to help people become the "best version of themselves".

Mike said: "CAST initially was holding a broken bone in place until it could heal. Now what we've been able to do is help really empower people to be the best version of themselves.

"We treat addiction, psychiatric disorders, anxiety, depression, and in a different program we help people who just want to be better. Who want to do better in their job, they may be struggling in their marriage, and so we help a wide range."

And Mike admits he believes Demi is a "miracle", as she's overcome her issues and is now able to talk about them publicly.

He said: "Demi has done a complete 180. She's the biggest pop star on the planet who talks about her issues in a public way. That is a miracle in the entertainment biz."

And the 'Skyscraper' singer is determined to use her voice for more than just singing, as she said previously she wants to use her status to "help people".

She said: "It sounds ridiculous but, like, I kind of made a pact with God.

"And I don't even think you're supposed to do that, but I was, like, I promised, 'If you make me a singer one day, I'm going to use my voice for so much more than singing, and I'm going to help people with it.' "
