Nearly a month after his release from prison, Dr. Conrad Murray has decided to break his silence in a bizarre interview with the Daily Mail.

Murray made a shocking revelation by revealing that pop legend Michael Jackson was a drug addict (who killed himself due to a drug overdose). He went on to say that on numerous occasions [he] had to hold the singer's penis up for him to urinate.

According to the DailyMail:

Murray says, "You want to know how close we were? I held his penis every night to fit a catheter because he was incontinent at night. He wore dark trousers all the time because after he went to the toilet he would drip for hours."

And there's this mystery ... Murray says, "Michael didn't know how to put a condom on, so I had to do it for him."

Murray also discloses some of the things TMZ revealed years ago -- that Murray believes Michael killed himself. Murray claims when he walked out of Michael's bedroom the day he died, "I believe he woke up, got hold of his own stash of Propofol and injected himself. He did it too quickly and went into cardiac arrest."

And, Murray suggests, MJ's kids have 3 different fathers, and Michael isn't one of them. Murray says, "Michael told me he never slept with Debbie Rowe."

And, Murray insists, Michael told him he had been sexually assaulted by one of his doctors while under sedation.

Murray suggests Michael predicted he would die on Murray's watch. He says MJ once looked at him and said, "You know, for the rest of your life and my life our names will become inseparable." Murray says MJ smiled and said, "I am clairvoyant."

After getting a hold of the reports, Michael's mother Katherine Jackson quickly became furious at Murray for spreading lies about her son and responded through her lawyer with:

"He's a coward who is trashing the man he killed for profit.

One of Katherine's lawyers tells TMZ, "Murray has refused to go under the OATH KNIFE and his attempt to exploit Michael are despicable and disgusting." Translation: He took the 5th because he's guilty as sin and now he's selling sordid stories about MJ to line his pockets.

Another lawyer sent Murray's attorney a scathing email, calling the doc "reprehensible."

But Murray's lawyer, Valerie Wass, quickly went on the counterattack, saying, "You and members of your client's family have been bad-mouthing my client for a long time. I don't blame him for talking, especially after ... you tried to portray him as an awful person."
