Singer Lady Gaga, who finished her `Cheek to Cheek` tour earlier this month, is working hard to continue to get in shape for her role in "American Horror Story: Hotel".

The 29-year-old took to Instagram on Wednesday to share with fans some photographs of her workout regime, reports aceshowbiz.com.

In one of the images, Gaga looks slightly tired while working out with a machine at what looks like a training room. She is seen wearing a black ensemble, paired with a cap of similar hue, while flaunting her toned abs.

"Gyro class, not the Greek sandwich kind,` she captioned the image.

Besides that, the "Born this way" hitmaker can be seen doing an intense abs workout in another photograph. The black-and-white image was captioned: "Horror Story Slave".

`Hotel" is scheduled to premiere in October. Apart from Gaga, the show also stars Naomi Campbell, Matthew Bomer, Sarah Paulson, Kathy Bates, Angela Bassett and Evan Peters.
