Silly question, is there a difference between a wedding shower and a bridal shower?

My friend is hosting her own bridal shower. I'm one of the bridesmaids, but before we could plan anything, she told us she already planned it.

She even has two registries for her bridal shower...at Williams Sonoma and Tiffany's. The cheapest thing on there is $200. What on earth? Is it normal to have a registry for a bridal shower?

I'm not looking forward to it at all.
