Lady Gaga participated in a steamy threesome on the latest episode of "American Horror Story: Hotel."

The 29-year-old "Born This Way" singer showed off her wild and sultry side on Wednesday night's episode, titled "Flicker," according to the Daily Mail. She was seen kissing women, exposing herself while flouncing around naked.

A flashback in the episode revealed Gaga's character The Countess in the 1920s as an aspiring actress, before she became a vampire. She stripped down for a scene with two old Hollywood actors, Rudy Valentino (Finn Wittrock) and his wife Natasha (Alexandra Daddario). Wittrock's character seems to be a reference to Rudolph Valentino, who was an old Italian star from the period.

In another scene, some workmen also found a secret corridor in Hotel Cortez, prompting Will Drake, played by Cheyenne Jackson, to tell them to explore it.

"It smells like death," one said before being attacked by two starved vampires, who end up being Rudy and Natasha.

Another development in this episode included detective John Lowe, played by Wes Bentley, who is undergoing psychiatric evaluation in a Los Angeles facility.

"I feel like everything is closing in on me, setbacks at work, separation from my wife ... my daughter is afraid of me," he told his therapist. "I attacked the only friend I had."

While in the hospital, Lowe entered room 153 after knocking out a security guard. He found a young girl with blond pigtails named Wren (Jessica Belkin) inside. A flashback was then shown in which Wren slit a security guard's throat.

"They were going to catch him," she said, referring to the evil killer she was protecting. "It is my fault ... everything that happened."

Another flashback showed Wren trapped, left alone in a hot car by her father. The Countess rescued her by smashing one of the car windows.

Back in the room with the detective, Wren said that she would lead him to the killer if he helped her escape the hospital. As they leave the hospital, however, Wren suddenly jumped in front of an oncoming truck.

In another scene, The Countess and Iris, played by Kathy Bates, stared down the secret corridor. The flashback played, showing The Countess in a threesome with the couple and later being told Valentino has died. After she married the evil Mr. March (Evan Peters) for his money, Valentino and his wife reappeared, approaching The Countess with news they were vampires. When they asked her to join them "in eternity," The Countess accepted without hesitation.

"American Horror Story: Hotel" airs on FX on Wednesdays at 10 p.m. ET.
