Lady GaGa is to star in U.S. Tv series American Horror Story's fifth season.

The Poker Face singer has been added to the cast for American Horror Story: Hotel.

Gaga announced the news on social media on Wednesday (25Feb15) by posting a creepy video online and captioning it, "Make your reservation now. #GagaAHSHotel."

The show's creator, Ryan Murphy, also shared the video.

It won't be the singer's first acting role - she had a small part in the 2013 action film MAChete Kills.
