Lohan is down! Lohan is down!

Super-skinny star Lindsay Lohan prompted yet more fears for her health after she reportedly collapsed at her LA gym. The Mean Girls star was halfway through an hour-long spinning sesh when she became pale and began gasping for breath. She stumbled off her bike and then collapsed, say Heat magazine.

"Everybody was shocked," one witness said.

"Lindsay wasn't moving and she appeared to be unconscious."

Thankfully her quick-thinking gym partner Kimberly Stewart and staff at the LA's Body and Soul gym soon brought her around. The drama ended after a few minutes, when a pale and woozy Lindsay assured onlookers she was fine. But the incident has sparked fears that her fitness regime was dangerous for her health.

Our first reaction was intense, instinctual, sympathetic: We emitted a high-pitched scream, then overturned every piece of furniture in a hysterical search for a telephone we could use to send ambulances to every gym in town. But once we realized that this incident is long over, our heart rate fell, and we were overcome by the powerful image of Lohan's publicist picking up yet another magazine featuring a cover expressing concern about the starlet's recent weight loss, hitting "LL" on the speed-dial, then commanding her young charge to take a dive off the first exercise bike she walked past.

And thus "exercising too hard" became the new "puberty."

Yes, we know. We're awful, awful people.

UPDATE: Wow, this is an old story. That's either the last time we begin an ether binge on a Thursday, or trust Sky for "breaking" news.
