Amy Winehouse fell over while navigating the treacherous corridors of her home Saturday, and as of yesterday remained in a private London clinic.

These things happen when you're Amy Winehouse ... or Lindsay Lohan.

"It was just a domestic accident and not serious," her spokesman, Chris Goodman, reassures us. "She bruised her ribs and had a cut above an eye."

Not clear at this time? Whether Blake Fielder-Civil or her other trusted associates Johnny, Jack or Jim were present when the latest spill occurred.

Also unclear? Which of the above figures is a poorer influence.

As for why such minor injuries would warrant an extended stay with the doctors, we honestly have no idea, but it's Amy Winehouse. Anything goes.

"I don't know if she's still there," her rep, who always works OT, said. "If she is, it's not because something has happened. It's because it's nice."

Because it's nice? Huh? Did this guy raid her stash of crack rocks?

The UK's Sun (we know) poses the theory that the latest tumble taken by the singer caused some bruising to her newly-purchased breast implants.

Sorry for posting this so close to lunchtime on the East Coast.
