Creed's lead singer Scott Stapp nearly ended his own life as he struggled with substance abuse, but he says he was saved by an unlikely person - the rapper T.I.

During a promotion tour to discuss his new autobiography, "Sinner's Creed," Stapp related the tale of how T.I. helped him to pick himself back up - literally - and find a path to recovery.

Stapp had checked into a penthouse room at the Delano Hotel in Miami, Fla., during a drug binge. He had been awake for three whole days in a row and said he was in "a prison of alcohol and drug addiction."

Things got progressively worse, and Stapp tried to end his own life, he said.

"I thought I was in 'One Flew Over the Cuckoo's Nest,' in an asylum," he said. "I started hearing things, like the cops were coming through the door and I started thinking, 'I can't embarrass my family.' So I was trying to climb over the balcony and fell 40 feet."

As a result of the fall, Stapp broke bones in his skull, hip and nose. He couldn't move or pick himself up from the concrete.

Then his savior appeared.

"I laid out there for two and a half hours and my guardian angel showed up-rapper T.I.," he said. "He immediately took care of the situation and saved my life."

Stapp and T.I. had met each other once during a brief interaction in 2004.

"I had met T.I. back in 2004, we were both writing songs for 'The Passion of The Christ: Songs Inspired By' soundtrack and we had briefly interacted there and knew what each other looked like," Stapp said. "We'd talked about being fans of Alabama."

That Alabama connection resurfaced when T.I. found Stapp motionless in a pool of blood.

"He walked in, and I found out later it was the only room left in the hotel and he came in off the street and came out, and as I'm laying on the ledge, blood fell to [T.I.'s] feet and he looked up and he had an Alabama hat on," Stapp said. "I said, 'roll tide,' and then he looked at me and put two and two together and really saved my life."
