I was shocked and saddened to hear of the passing of Johnson & Johnson heiress and frequent tabloid guest star Casey Johnson. She was found yesterday morning at her home in LA, and authorities say she’d been dead for some time before that. Casey adopted daughter Ava from Kazakhstan in 2007, but she had been living with Casey’s mother because Casey couldn’t get her drug problem under control. The LA County coroner said that he did not suspect foul play in Casey’s death, and the cause of death would not be known for several weeks, while they wait to get the toxicology results back.

I don’t have it in me right now to do the entire drug rant again. But, look, if being a beautiful, thin, wealthy mother with all the opportunities and options and doctors in the world can’t save your life from the terrors of a drug addiction, how much better do you think your own odds are? Just don’t do it.

Most people don’t seem to know who Casey Johnson, the Johnson&Johnson heiress who passed away yesterday, but Paris and Nicky Hilton sure did. The fellow heiresses were family friends with Casey and according to Paris’ Twitter eulogy, this is not easy news for them to hear. While Paris Tweeted her condolences, Nicky Hilton, her mom Kathy and her boyfriend David Katzenberg went to the Johnson home last night to offer their support.

No one seems to be taking the news as hard as Casey’s future wife, Tila Tequila. In fact, she’s so upset that she just can’t stop Tweeting about it. Here are some of her Twitter posts from last night:

I know u can feel me Casey! Dot let go! I’m almost home baby please hang on! We have a beautiful life planned out for us! I LOVE u! Hang on!

I’m still in shock! Once again thank U for the outpour of love and support. I just wish to have some privacy at this heartbreaking time.

R.I.P my Angel. @caseyjonsonJnJ u will forever be in my heart! I love u so so much and we will Marry when I see U in Heaven my Wifey

I can’t stop these haunting visions of her and I. We made such a lovely couple, only beginning to spend the rest of our lives together…

It’s nice that she took a night off from the computer and whatever the hell she’s on to just grieve, right?

As for the cause of death, we’re still waiting and it looks like we’re going to be waiting for awhile. Because of the high-profile nature of her case, Casey’s autopsy results have been sealed and won’t be released until about a month from now. There’s a chance that the family may make an announcement before then and we will definitely hear rumors, but nothing official should be released for awhile.

The common COD is widely believed to be drug use, but it may also be diabetes related. Wow, that sounds awfully familiar.

Casey Johnson, Johnson&Johnson heiress and “wifey” of Tila Tequila, died today in her Los Angeles home. The 30 year old was found in her bedroom by her maids. A neighbor reported to E! News that when her body was discovered, the maid screamed “She’s dead!”. As of right now the cause of her death is still undetermined.

Tragically, Casey adopted a little girl, Ava, from Kazakhstan in 2007. Most recently she’s been popping up on Twitter as the fiancée of Tila Tequila, who left this statement for her fans today:

I’ll keep you updated as more details roll in tomorrow.

I am doing my part to keep Courtenay Semel in the spotlight for as long as possible, just because I am certain one of these days she will do something so absolutely insane on camera that it will make it all worth it. Honestly, eventually she’s just going to snap and, like, tie Nicole Richie to a leather sofa and cover her in honey and fire ants and film the whole thing on a CoolPix camera and email it to Nikon demanding a sponsorship. She is that kind of crazy.

Here’s the former lover of Lindsay Lohan, Tila Tequila and Lord knows who else, at Sundance with her current flame, heiress Casey Johnson, whose hair seems to be recovering well from when Courtenay set it on fire earlier this month.

Courtenay Semel, the uber-rich, alcoholic, drug-addicted, but-her-faced, hot-tempered, celebrity lesbian love interest du jour, has just burned her (equally crazy) ex-girlfriend’s hair off.

CASEY Johnson – the madcap Band-Aid heiress whose father, Woody Johnson, owns the Jets – is said to be wearing her hair in a short, butch style following a vicious catfight with her ex-girlfriend, Courtenay Semel. “Casey had a fight one night with her current girlfriend,” heavily tattooed Lisa Marie Alvarez, a Los Angeles source, told Page Six. “Casey went to Courtenay’s house, and Courtenay proceeded to beat the crap out of her, and then she lit her hair on fire. Casey had to be hospitalized.” Casey’s mother, Sale Johnson, reportedly flew to LA and consulted with lawyer Robert Shapiro. No one returned calls except Courtenay, whose father Terry Semel ran Yahoo for years. “There was a fight,” Courtenay said. “But this is a major exaggeration. We are speaking. We are friends.” Casey – who isn’t speaking to her father, or her aunt, Libet Johnson – is the mother of an adopted girl from Kazakhstan.

OMG. These girls are such headcases. I swear, all the money in the world does not buy happiness. In fact, it just seems to encourage low self-esteem and crazy. The next time you think to myself, “Man, why couldn’t I have been born an heiress?” just keep these girls in mind.
