What's with the wig Christina Ricci?

Christina Ricci, who made headlines recently when she chopped off all her hair, stopped at her local gas station for a quick coffee yesterday in Los Angeles looking totally different again! We can't keep up with all these celeb hair changes! Christina rocked a pig tail braided wig and a large pair of shades, we are wondering if she was trying to avoid the paps for one day with a different look? Sorry Christina, there is just no mistaking you! She has such a destinctive look, you would notice here anywhere!
