Gia P. is making this up. Has to be.
Conclusion based on fundamental law of porn Numero Uno:
Whores Lie.
See, she has to be making the whole story up because the law says so. I rest my...waitaminute!
Sierra say she didn't take the shoes or powder; since she is also a whore, she must also be lying. Right?
So, Gia P. is lying about shoes and make-up that were not stolen by Sierra who is lying about not taking them.

What?!?

Uh, now my brain hurts. I'm going to go lie down.
