Looks like Season 6 of “American Horror Story” is shaping up to be the FX anthology’s scariest installment yet. Although the creators behind the thrilling series are keeping tight-lipped about the plot of the forthcoming season, a few secrets have slipped through the cobwebbed covered cracks … like who will star in the anticipated sixth season.

During the Television Critics Association summer press tour, Sarah Paulson, who’s starred in every season of “American Horror Story” (since the 2011 premiere), confirmed her participation in the spooky sixth installment. Paulson is the fourth “American Horror Story” alum to verify that they’ll be scaring audiences when the series returns to FX in the fall.

Cheyenne Jackson revealed in June that he would return to the “American Horror Story” set. But Jackson isn’t the only Season 5 star slipping back into the horrifying storyline. Lady Gaga, who received a Golden Globe for her role as the Countess in “Hotel,” is additionally making her way back to the chilling drama.

In March, the mother of monsters dished to New York’s hit radio program “Elvis Duran and the Morning Show” that she would giving fans nightmares once again. “I can’t promise you how or when or anything like that,” the actress tried her best to not unveil any further details of her eerie, upcoming role. A month before Lady Gaga confirmed her return, Angela Basset let the news slip that she was starring in Season 6 of “American Horror Story” during an interview with Larry King.

Although the four actors announced that they’ve been cast to star in the sixth installment, each artist has kept quiet about what character they’ll play when “American Horror Story” premieres Sept. 14. All that is known about Season 6 is that it will be “set in the present” with “echoes of the past,” according to FX president Jonathan Landgraf. “It’s set in two time periods but principally in the present.”
