It's no secret that Michael Jackson was on numerous medications, but was a powerful sedative to blame for his shocking death last week?

According to the Associated Press, Jackson repeatedly begged his caretakers for Diprivan (aka Propofol) despite warnings it could be harmful, and it's now being reported that the drug was found in his Holmby Hills estate after he died.

Cherilyn Lee, a registered nurse who worked closely with the pop icon said that she repeatedly rejected Jackson's demands for the drug, which is a powerful intravenous anesthetic widely used in operating rooms to induce unconsciousness. However, it appears as though Jackson found another way to get it, and we have to wonder if he might still be alive today if he hadn't gotten his hands on the drug.

Dr. John Dombrowski, a member of the board of directors of the American Society of Anesthesiologists told the AP that an overdose that stops breathing may result in a buildup of carbon dioxide, causing the heart to beat erratically, leading to cardiac arrest. Add painkillers (such as Demorol, which Jackson was also taking) to the mix, and you've got a recipe for disaster.

Lee received a call from a Jackson staffer just four days before his death, and she tells the AP:

"[The staffer] called and was very frantic and said, 'Michael needs to see you right away.' I said, 'What's wrong?' And I could hear Michael in the background... 'One side of my body is hot, it's hot, and one side of my body is cold. It's very cold.' I said, 'Tell him he needs to go the hospital. I don't know what's going on, but he needs to go to the hospital...right away.' At that point I knew that somebody had given him something that hit the central nervous system. He was in trouble Sunday and he was crying out."

However, Jackson did not go to the hospital, and while an official cause of death still hasn't been determined, it sure looks like this might have been the medication that pushed the reportedly frail Jackson over the edge....

We reported earlier that the King of Pop will return to Neverland Ranch, his Santa Barbara estate, on Thursday morning for a public viewing the day later. (A private service is scheduled for Sunday, two days after that, as July 4th falls in between.)

X17 photogs just got off a 2-hour flight to the ranch and we can confirm that preparations are indeed underway... An X17 photographer tells us:

"There were at least thirty workers preparing the grounds for the big event. There were landscapers outside, people coming in and out, cleaning and preparing the house. And there was a police cruiser on the property, monitoring the perimeter."

Sounds like a lot of activity going on! While we understand the need for fans to say their goodbyes to MJ, we can't help but wonder... how will this all go down? The area is certain to be flooded with people wanting to pay their respects - but can security keep the chaos under control? And should such a viewing even have been allowed? And what about that 30-car LAPD escort just to get the body up there? Are us taxpayers paying for that?!

Our photographer adds: "All the carnival rides have been removed. The grass was finally being watered. The place was bustling with activity but it was definitely coming together - this old, dead property is coming alive again."

Neverland is about to turn into Graceland! Stay tuned for pix and more info, coming ASAP!

What better way is there to spend a Monday afternoon?

Beverly Hills socialite slash reality TV star Kim Kardashian, accompanied by a gal pal, hit up the Chanel store for a little retail therapy. Hmm, but doesn't she have enough clothes already?

Nah! You can never have enough clothes! Obvs.

Justin Timberlake has some more words to say about his late idol Michael Jackson - the Prince of Pop talked to MTV U.K., reflecting on his memories of the "Thriller" singer. (Jackson performed with 'N Sync at the 2001 MTV Video Music Awards...)

JT says in the vid below:

"The thing about Michael is the memories. I'm lucky enough to have memories - actually, physically - with him, onstage and off. It's a testament to how big a deal it is, obviously, because he's created so many cultural photos in people's minds with his music that he really was and always will be the king of pop."

Hmm, think the reports are true that he'll help take over for MJ's 50 London concerts?

Kate Moss and her rock star du jour, Jamie Hince were snapped leaving Prada in Paris earlier today, and we're not sure who all the loot was for, but the two seemed to be having a blast! Think it was his 'n hers, or is it all for Kate? And more importantly, who paid for it?

Move over Megan Fox AND Isabel Lucas - if I see Transformers 2: Revenge of the Fallen, it'll be because of mega-hottie Josh Duhamel!

Fergie's hubby is in NYC and he was kind enough to sign autographs and greet fans the other day... what would you say if you met THE Tad Hamilton???

The AP report that a copy of Michael Jackson's will (from 2002) has finally been received by the Jackson family.

X17 reported earlier that the doc, held by Michael's lawyer John Branca, divides MJ's estate between his mom Katherine, three kids, at least one charity... and makes no mention of father Joe.

Do you think Michael equally distributed his assets?

Nicky Hilton made a stop at a local gas station yesterday afternoon, and we're not sure if she stole this dress from her big sister or from a children's clothing store, but she sure is showing a lot of skin! I mean, look at the way that thing fits...who knew Nicky owned such a dangerous outfit?
