Britney Spears, You Oughta Know Better

We often critique stars who won't sing in concert ... or at all. But perhaps at a certain point, lip synching isn't the most terrible concept ever created.

Britney Spears attempted to pull off a cover of Alanis Morissette's classic "You Oughta Know" during her concert Saturdya night in Greensboro, N.C.

The jury's still out on whether it was actually pulled off. Or if any fans were ejected for risque dancing. Man, this song makes you wanna lose yourself.

While it was by no means good, we admire her chutzpah, and the superstar's choice of song. Better than covering a Lady Gaga track or something.

Did Britney nail it? Or should she oughta know better than to try to sing? Check it out and see ... and pray Heidi Montag doesn't copy her hero next:
