American Horror Story: Hotel Brings Back Murder House

"American Horror Story: Hotel" is going to have a plot twist that will look very familiar and awesome to fans -- Ryan Murphy is returning to the infamous house that launched the horror series.

We were outside the Victorian style L.A. mansion on Wednesday when Lady Gaga came cruising out hiding her face, but we know she was there to shoot 'AHS' scenes.

Murphy had hinted the 'murder house' might be involved in the new season -- but our shot of Gaga makes it a lock, plus there were other clues. The previously dilapidated home now has fresh landscaping, a new wrought iron gate, and old timey cars ... a big hint the haunted house will appear in a flashback.

Killer twist ... enjoy our shots from the set.
