Is Lady Gaga taking style cues from our favorite "Batman" baddie?

The singer looks (O)-positively killer in these new photos from the set of "American Horror Story: Hotel" -- but one in particular has us grinning maniacally from ear to ear. In it, Gaga resembles Gotham's own nefarious supervillain, The Joker, as she feasts on human blood. You know, it's just another casual Thursday at Hotel Cortez.

Gaga's character, The Countess, is being billed as "a glamorous socialite who attends art openings and fashion shows" and maintains her gorgeous looks from drinking -- you guessed it -- human blood. Vegan diets are so passé these days.

"It's really a form of hemophilia, in a way," Ryan Murphy explained to Entertainment Weekly.

The Countess and her two lovers, Donovan (Matt Bomer) and the Tristan (Finn Wittrock), will indulge in these bloody cocktails -- but they won't be the only ones. Thanks to EW, we now know Gaga's Countess will have a brood of bloodsucking children (that she "kidnapped/adopted") alongside her at Hotel Cortez.

"They are the most important thing to her," Gaga told the magazine. "More than anything, I think she wants to identify in a very human way."

Aww. That almost makes up for the murdering people part.
