Lindsay Lohan 's ex multi-millionaire boyfriend Harry Morton reportedly died of an undiagnosed heart condition, according to grieving family and friends.
The Pink Taco owner's family revealed the preliminary test results on Tuesday after he was found dead at his $25million Beverly Hills home at the age of 38.
His family claim a medical examiner told them the business mogul had coronary disease and a mildly enlarged heart, unbeknown to him as he died of sudden cardiac arrest.
They've also denied his death had anything to do with drugs.
New details emerge after friends told MailOnline about how Harry was allegedly addicted to a powerful hallucinogenic used by shamans.
However, some of Harry's close family and friends deny the claims and according to The Sun , Los Angeles County Sheriff's department have confirmed he had no drugs in his sytem.
The successful businessman was pronounced dead at the scene after being discovered by his brother on Saturday.
The son of Hard Rock Cafe founder Peter Morton, 72, is unable to have a funeral until further tests are completed.
These include a microscopy of his organs, a source told Page Six . The family are planning a memorial service for him on Saturday.
Harry enjoyed a meal with his family - including his dad - the day before his death and seemed to be in good spirits.
Friends claim he was a well-known drug user and regularly took ayahuasca - made with tropical plants from the Amazon jungle.
The drug distorts brain waves to create a vivid "waking-dream" state.
It was used by his ex Lindsay, who used the drug to help her cope with a miscarriage.
She led tributes to her ex and shared a photo of the pair back when they were dating with the caption: "Best friends. Best life."
Lohan's mum Dina reportedly paid tribute to the star on Instagram , writing: "RIP Harry God has an angel, we love you! Prayers to the family."
A representative for Lindsay Lohan has been contacted by Mirror Online for comment.
