The Born This Way hitmaker is among the newcomers joining the cast for the latest instalment of the U.S. TV thriller franchise, and on Saturday (15Aug15), she hosted a bash for her co-workers and took to to share snaps of her gory set-up.

In one snap, the singer showed off her backyard pool, full of dyed red water and wrote the caption, "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."

Additional photos showed off Gaga's crystal chandelier adorned with red roses, a golden bust of a crying woman, and one of the hostess herself, posing in a diamond-studded gown in her candle-lit living room.

American Horror Story creator Ryan Murphy took to Twitter the next day (16Aug15) to share his thoughts on the party, writing, "Last night I had a dream that the HOTEL cast went to Gaga's house and at midnight swam in her pool that she dyed blood red just for us.

"Wait a minute, that was no dream...THAT ACTUALLY HAPPENED."

Co-star Sarah Paulson replied to Murphy and said, "WAIT. I HAD THE SAME DREAM..."

Meanwhile, another returning star, Kathy Bates, shared her praise for the pop star, and tweeted, "Was it Norma Desmond, Jean Harlow or Marilyn Monroe descending the staircase towards me in a shimmering silver gown? No, it was @ladygaga!"

Gaga is set to play the owner of the cursed TV hotel, while Bates runs the day-to-day business and Paulson is a permanent resident of the venue.
