Jason Donovan has described his collapse at Kate Moss' 21st birthday party as "through the roof embarrassing"

However, Donovan started a drugs binge "two or three days before" the party and ended up collapsing on the dance floor before being carried out of the venue by paramedics and he still feels shame over the incident. Speaking on the Great Company podcast, Donovan explained: "I flew in from Australia and scored some cocaine and it was pretty good quality.

"I mean, that is the truth you know and I 'got on it' as they say, and that was two or three days before the event.

"Suddenly, I found myself amongst all of these very famous people ... and I just found myself overeating, shall we say."

Donovan collapsed while Depp was performing a rendition of Van Morrison classic Gloria with Hutchence and the party was stopped so he could get help.

He explained: "This soap star from Australia who had been on a bender for two days suddenly finds himself in a stretcher with the room closed down and the lights gone up.

"Nothing to be proud of. [It was] through the roof embarrassing."

However, the Neighbours star admits the incident didn't put him off drugs. He added: "I got back on it straight away. I had the money and the ability to do what I wanted to do."

He said of his years of drug abuse: "My drug take was more binge but long binges - like, three, four days. I think I went four days without sleep once. I used to have seizures, too."

Donovan finally got clean after meeting his wife Angela Malloch and welcoming his first child, daughter Gemma, now 25.

He said: "You've got to want to change yourself. There are catalysts and, to cut a long story short, for me it was the birth of my first child and meeting my wife. That was the get-out clause I was waiting for."

The actor is also dad to Zac, 24, and Molly, 14, with Malloch, who he married in 2008.
