DEMI MOORE WAS SMOKING SOMETHING THAT WASN'T POT: An edited version of the 911 call that preceded DEMI MOORE'S hospitalization last week hit the Internet over the weekend, and from it we've been able to determing Demi was smoking something.

We just don't know what.

In it, an unidentified woman says Moore smoked something that was NOT marijuana and that she was having convulsions. A second woman then gets on the phone and when asked what she took, the woman says, quote, "Some form of" . . . but whatever she says next is edited out.

SO WHAT *WAS* DEMI SMOKING???: Was it the legal hallucinogen that MILEY CYRUS was caught on video smoking back in December of 2010SALVIA that sent DEMI MOORE to the hospital last Monday? That's one of the theories being floated this morning.

Another possibility is that Demi was toking spice -- a synthetic form of pot also known as K2 or herbal incense. According to "Us Weekly", some medical studies have linked spice to, quote, "psychosis, heart attacks and convulsions."

Meanwhile ... Rumors are still lingering that Moore was doing whip-its at the time. TMZ claims that mention of nitrous oxide was edited out of the released call because of privacy issues. Of course they're the ones who reported Demi was doing whip-its in the first place. That has yet to be confirmed.

COULD BE TRUE, BUT PROBABLY CRAP - KIM KARDASHIAN HAS SET HER SIGHTS ON TIM TEBOW!!!: This is so presosterous it's probably no where near being true, but it's also too ridiculously good to pass up.

The "National Enquirer" claims KIM KARDASHIAN is trying to get her hooks into TIM TEBOW!!! According to their source, Kim is not only totally crushing on Tebow, but, quote, "needs to rehab her image to get her career revved up again. Dating someone like Tim Tebow would certainly do the trick."

Tim is supposedly aware of Kim's crush and is "flattered", but "not interested." Says the source, "He's an avowed virgin who's saving himself for marriage and is looking for a woman with similar values, not someone with two failed marriages AND a sex tape in her past."

On a related Kim K. note ... The "Kourtney & Kim Take New York" season finale that showed Kim deciding to end her marriage with Kris Humphries aired last night. In it, Kim is shown finally breaking down to Kourtney, sobbing, "He's a good heart, he's a Christian -- everything on paper I want in someone, but for some reason, my heart isn't connecting."

"He fell in love with me and I fell in love with him and now all my feelings have changed...I invited all these people to this huge wedding and flew everyone out, wasted everyone's time and everyone's money -- everyone's everything -- and I feel bad."

They didn't show the actual split, though. The show ends with Kim and Kris leaving New York on a near-silent ride to the airport, with Kim adding, "I wanted to be married by 30, and everything I envisioned my life to be is not the fairy tale I wanted it to be."
