(Update: Turns out Demi was actually hospitalized after huffing nitrous oxide. Really, whip-its? You’re a millionaire, not a 13-year-old boy loitering behind a Missouri Walmart.)

Whyamisotired.com explains “exhaustion” as follows:

Most people feel tired after a busy day, but bona fide medically diagnosed exhaustion is something else entirely. Exhaustion may also be described as fatigue, languidness, lassitude, listlessness, lethargy and languor. Fatigue or exhaustion symptoms are reported by the patient as opposed to being something that is observed by others, which would be a sign instead of a symptom.

Okay, so now I’m more confused than I was, although likely the person writing that was suffering from being retarded.

Demi and Tracy are just the latest to come down with exhaustion. There is a veritable army of celebrities who have checked themselves in to hospitals because life was too tough at the top of a pile of money.

Mariah Carey

Back in 2001, Mariah Carey checked into a hospital because she was tired. I’m sorry, “extreme exhaustion,” which is probably exhaustion dyed bright green, base jumping. She did it again in 2002, and her PR people assured the world that it was because she was overworked, and totally not because she was having psychological problems, which, of course, means she was likely losing her shit. Her PR people apparently come from the school of thought where they think the best way to divert attention from something is to call attention to it. If she had publicly crapped her pants, they would have said she changed her pants due to exhaustion, not because she shat herself on stage.

Selena Gomez

As bad as I would love to rip on her, I will take it easy on Ms. Gomez. First off, she’s just a kid (what is she? 15?), and I do buy that a barely-legal girl who has spent the last several years in front of a camera might actually be malnourished. It’s not like mom set her up to make the best decisions, seeing as how her mom stuck her with freaking Barney when she was 10. That type of thing leads to all kinds of “different” behavior, like dating other girls. Kudos to her mom for being open minded, though. I’m sure Justin will one day make Selena a great wife. Just get the kid a damn cheeseburger.

Winona Ryder

Many Hollywood bad girls get involved in garden variety pursuits like drug or alcohol abuse. But Winona Ryder did something that, in its own way, is even worse: shoplifting! When a millionaire movie star is stealing clothes just for the thrill of the crime, you know she’s stolen a seat at the Hollywood Bad Girl Hall of Fame.

Madonna

Unlike many bad girls in Hollywood, Madonna is a shrewd professional in all aspects of her career. Rather than going out of her mind, partying, stealing boyfriends, etc., she pretends to do all of those things, and more, as part of her public persona. But have you ever seen her do “Like A Virgin”? If she’s not a Hollywood bad girl, than nobody is.

Lindsay Lohan

One of the definitive Hollywood bad girls, Lindsay Lohan took the enormous promise she showed as a young child actress and squandered it on sex, drugs, and alcohol. Ain’t that always how it goes? She may be in line for a comeback, though, so don’t rule her out just yet. If her adult performance in Robert Altman’s A Prairie Home Companion is any indication, she still has talent to spare.
