Liam Payne is alleged to have suffered drug addiction in the year before his death.
The One Direction singer fell to his death, aged 31, on October 16 from the third-floor balcony of his room at the Casa Sur Palermo hotel in Buenos Aires, Brazil, with his suite reportedly littered with drugs paraphernalia.
His friend Roger Nores has now said in a long court filing obtained by Page Six the performer was voluntarily in and out of rehab centres for nearly 12 months in an attempt to “overcome” his apparent battle with substance abuse.
He said in the papers: “I was a friend who loved him very much, who helped him selflessly in everything I could, who spent my own money to help him, and even then it was not enough.
“I do not consider that I deserve the accusation that is being levelled at me.”
