Cole said Winehouse shouldn't have been trying to perform

Her treatment facility gave her a brief reprieve so she could perform for a worldwide audience and receive her accolades.

Cole said the entire episode sent a bad message. "Her life was at stake. I mean, she was trying to get off heroin, which is probably one of the most difficult drugs to recover from," Cole said.

"I just don't get it. What more can we do other than everybody needs to grow up? Hollywood needs to grow up and stop glorifying this kind of behavior and thinking it's cute," she said.

Cole said Winehouse shouldn't have been trying to perform, given her condition. Winehouse had been in and out of rehab and battled a host of problems since her Grammy triumph, had not released another album and was performing only sporadically.

Pax Prentiss, founder of the Malibu, Calif.-based Passages treatment center, said it's often in an addicted performer's best interest to be working, rather than living an unstructured lifestyle without getting help.

"It keeps them busy. ... I don't think it's good to have idle time," said Prentiss, a former addict himself. "But in saying that, Amy was not ready to go back to work. ... She clearly was not ready for the stage, or for life in general."

Winehouse's management and record label did not respond to requests seeking comment for this story.

Prentiss said Winehouse's problem may have been that the underlying causes leading her to take drugs were not dealt with. But he added that he didn't think the music industry "should try and manage Amy's personal life."

Cole disagreed. She said the industry has a responsibility to step in and push an artist out of the spotlight until they get their personal act together.
