The former Wimbledon champion said he became addicted after he accidentally swallowed $960,000 of the drug after mistaking it for a new kind of Robinson's barley water.

He then spent the next decade gradually removing his hair in exchange for a series of crazy highs.

Agassi said: "Most drug dealers are mad for celebrity hair. Pablo Escobar had a whole wig made out of Gloria Estefan clippings.

"Touring the world playing in tournaments, I wouldn't have enough local currency to get totally moonfucked on ice, so I'd have to barter with clumps."

He added: "I knew I'd reached rock bottom when I found myself in a Singapore back street tearing out huge handfuls of pubes for a quick hit. I cried myself to sleep that night."

Tennis historian Wayne Hayes said: "His fans thought Andre got rid of that straggly pony tail because it made him look like an extra from a Wham video.

"But the truth is he was having a 30th birthday party and wanted a life-size statue of Rod Laver made entirely out of toot."

Agassi warned young sports stars of the harm illegal drugs had on his performance, adding: "How I got through the third round at Queen's in 1997 I do not know. I spent half the match swatting at giant purple bees with the face of Sue Barker.

"Thank God I was only playing Tim Henman. You might not be so lucky."
