VIDEO : Lady Gaga Throws House Party for American Horror Story: Hotel Cast With a ''Bloody Pool''!

Lady Gaga revealed in February that she joined Ryan Murphy's latest project American Horror Story: Hotel, and it looks like the star decided to throw a little get together for her castmates!
Gaga wrote with a photo of the set-up on Instagram, "A bloody pool for the cast, sorry #AHSfans, there's few pictures. At my parties, killer friends have more fun, when no evidence is left behind."
