Pete Doherty witnessed Amy Winehouse's overdose

According to reports, Pete Doherty was actually at the scene where Amy Winehouse had an overdose - which led to her near early death.

Doherty reportedly fled the scene minutes before the 'Rehab' star was rushed to hospital.

A source told Britain's Sunday Mirror newspaper: "They had a meal and a few drinks. They took a cocktail of drugs called a speedball, it's a mixture of heroin and cocaine. Amy couldn't take it, she is very lucky to be alive.

"She collapsed when they went back to her flat. Pete left because he didn't want any bad publicity. He didn't know how to deal with it and thought she was dying. She was foaming at the mouth and fitting - Pete had never seen anything like it."

Pete and Amy were introduced as mutual friends little more than a year ago, and since then, the pair have been seen drinking together on countless occasions.

They even allegedly spent the night together, when the troubled 'Babyshambles' singer was still shacked up with Kate Moss; Doherty refused to comment on the matter.

Instead, a friend said: "Pete said he wanted to see Amy because she was all alone in her flat. They were in there for hours. I knew something happened between them when I spoke to him the next morning. He wouldn't confirm he had sex with her, but he didn't deny it either."
