CB already covered People Magazine’s cover story this week – Demi Moore and her “dangerous desperation” to stay young and skinny. And now Us Weekly has revealed their cover story – which is also about Demi being desperate, this time about really young guys. According to Us Weekly (and HL), Demi has been trying to hook up with her daughter’s friend (and rumored boyfriend) Zac Efron. Poor Zac finds Demi “creepy” though. Hollywood Life also repeats that gross story about Demi “grinding” on Victoria Justice’s boyfriend’s ass. Fo’ real. You know who has my sympathy at this point? Rumer. That poor girl.

The night of Demi Moore’s Jan. 16 911 call was even scarier than it sounded.

“Everyone thought she was going to die,” a source tells the new Us Weekly of the emergency, in which Moore, 49, collapsed, and was “convulsing” after smoking an unknown substance.

It was the culmination of months of self-destructive partying (and drug use) for the newly single star, struggling to make sense of things as she nears 50 without husband Ashton Kutcher, from whom she split late last year.

“She’s been really down, and she’s surrounding herself with young people to make her feel better,” an insider tells Us of Moore, who’s been obsessed for years with staying young and thin.

“She’s been mixing pills and Red Bulls, among other things,” another source says.

One of Moore’s favorite young stars to party with — and flirt with — is daughter Rumer Willis’s longtime friend Zac Efron, 24, a hunk nine years younger than Kutcher, 33. Not only has Demi Moore, 49, ”literally inserted herself” into 23-year-old daughter Rumer Willis‘ social circle, but she’s even trying to hook up with 24-year-old Zac Efron!

“She calls him and texts him a lot, but he’s not interested at all,” a source tells the mag. “He thinks she’s a creepy cougar.”

A wired, gaunt Moore “tracked down” the High School Musical star at a party in L.A.’s Venice neighborhood, an insider tells Us. “She seemed out of her mind at this party.”

Meanwhile, People reports that Demi has yet another younger guy in her sights — Victoria Justice‘s boyfriend, 27-year-old Ryan Rottman!

“She found ways to touch him all night, and at one point when he was in front of her, she was grinding on his butt,” an onlooker said of Demi and Ryan’s behavior at a Jan. 11 party. “His shirt came unbuttoned, and she started tickling his bare chest playfully.”

For additional details on Moore’s spiral — her calls and texts with Efron, how her three daughters are coping, her ongoing obsession with staying young, and what’s next — pick up the new Us Weekly, on stands Friday.

I don’t even know what to say about this mess at this point. Demi clearly has significant issues, and this has gone beyond a simple public-relations problem, although I do think the root of Demi’s problem might be the dichotomy of how she views herself (hip, cool, young, relevant) versus the reality of who she is now (sad, desperate, kind of pathetic). I don’t think it’s as easy as saying “Demi needs to act her age.” This woman has mental health issues, and a good publicist can’t fix the crazy.

So what’s my armchair advice to Demi at this point? Go away for a while. Take a year or two off, don’t work, go back to Idaho or something. Don’t tweet. Don’t give interviews. Get clean and sober. Wear sweatpants for a while and stop messing with your face. Eat real food. And then, after some time has passed, come back. Relaunch yourself as smart and effective producer who still dabbles in acting. Give a few interviews, but only to the major outlets. Write a tell-all book, and really TELL ALL.

… But she won’t follow my advice, will she?
