The Internets are ablaze this morning with theories explaining Britney’s wooden performance last night.

Photographic evidence of a glittering broken heel is being touted as the reason Brit appeared to stiffly walk through the number, barely moving her hips.

X17 is reporting that Britney Spears was suffering an impediment of a more emotional nature:

A source tells X17 Brit found out about Sarah Silverman’s crappy line about Britney’s babies just moments before she took the stage to perform "Gimme More."

Needless to say, Britney was PISSED! … as any mom would be. Britney was so upset she walked through her performance just to get it over with (despite encouragement from her friends, including Sam who was apparently yelling at Sarah backstage) to skip out on it all together).

She held up her end of the bargain and got a major slap in the face from Sarah.

We’re sure other excuses for Brit-Brit’s uncomfortable-looking routine will continue to pop up today.

We’d like to float our own theory that Britney had her Cheetos power snack way too close to curtain call.

You simply cannot shake your money maker with real feeling when you’re still digesting such cheese-flavored goodness.

Even if you do somehow get the orange stains off your hands in time.
