Lady Gaga is putting in werk before she makes her boob tube debut. 

The 29-year-old singer took to Instagram on Wednesday to share a peek into her workout regime as she continues to get in shape for her forthcoming role in American Horror Story: Hotel

"Gyro class, not the Greek sandwich kind!!" the Mother Monster captioned the pic in which she's flaunting her killer abs as she workouts out with a fancy machine (the popular fitness method, which uses the same principles of yoga, consists of exercises that are said to balance the body's strength and flexibility). 

And apparently, the engaged beauty isn't holding back and is hitting the gym hard.

"Horror Story Slave," she captioned another black and white image which sees her doing an intense ab workout. 

It was announced in February that the "Born This Way" beauty will star in the FX anthology series. E! News has learned that the "Judas" singer will have not one, but two hot love interests on the show in the form of Matt Bomer and Finn Wittrock (swoon!). 

"She's a big fan," Gaga's fiancé Taylor Kinney previously told E! News of the singer, adding that his bride-to-be is "excited" to join the series. 

"She's the one who turned me onto it," he said. "It's a bit out there, but I love it. The performances, the writing, the cinematography on that show—across the board, I think she really wanted to be a part of it, so I'm looking forward to watching. I think everybody will be."
