BOY BANDER LIAM'S

Autopsy reveals Payne was flying on pink cocaine during deadly fall

- 

FORMER One Direction singer Liam Payne was so drugged up and acting crazy, a hotel staffer feared the boy bander might harm himself shortly before the star plunged to his death from the third-floor balcony of his room in Argentina.

Buenos Aires officials believe the 31-year-old singer, who reportedly promised his $60 million fortune to love child son Bear, 7, was alone smashed-up room when he plummeted, fatally in his cracking his skull on Oct. 16. An autopsy revealed drugs in his system.

"My life now is his, my money is his [Bear's]," Liam said two years ago. "I have actually got several companies that are up and running that I know he can run one day if he wants to or [he can sell them]."

The autopsy found 25 injuries to his body, but concluded the brain and skull damage "were sufficiently suitable to cause death."
