I have read A LOT about Gia (I was obsessed a couple of years ago). And nothing ever indicated that Sandy hit her! Of couse she wasn't a saint though, but when you see later interviews with Sandy and follow her yahoo-group about Gia, like I do, she seems to have loved Gia - and not just love of the platonic kind. Even if she consider herself straight.
You are right. It was Rochelle who hit Gia after she stole from her. That's when she ran on to the street half naked or something. Sounds completely cray.
Yeah, Janice sounded pretty emotional in the documentary. They were friends but Gia did give Janice a right hook once. She must have been doing her usual trash talking. Lmao! I bet a lot of people would love to do that!
