Maybe she spilled stuff from her purse while she was standing there pawing through it. Then got down to pick it up and fell only slightly - more of a drop than a fall.
But I thought I'd seen a photo of her lying somewhat on her side, and that would indicate a fall to me.
I think she fell too. I mean, at some point she was only wearing one shoe and those are like, 6 inch platform heels. It would be really tough to walk in just one. Then add in the alcohol - flexeril cocktail and a fall is just about guaranteed.
I never heard she got there with just one shoe. LOL. Does that mean she hobbled up to the house and into the living room with one shoe on and one shoe off? Man, I bet that was a sight.
