Lady Gaga & Matt Bomer Engage in Bloody & Racy Scene for 'American Horror Story: Hotel'

Lady Gaga shows some leg while exiting a building with her security detail on Wednesday (October 7) in New York City.

That same night, the 29-year-old entertainer made her big debut on the American Horror Story: Hotel premiere.

“Watching at home on the couch with my baby @TaylorKinney111 keeping me calm! �’��”�,” she tweeted.

We won’t get into the gory details – literally – but she did strip down for a bloody and racy scene with Matt Bomer, who also bared it all for the episode.
