Lady Gaga has been spotted attending a funeral on the set of "American Horror Story: Hotel."

The 29-year-old singer turned actress was seen wearing widow's garb while filming scenes for the FX show in Pasadena, California on Tuesday, Oct. 13, according to Daily Mail.

Gaga plays the role of Hotel Cortez owner Elilzabeth, otherwise known as The Countess, was escorted on the set in her all black attire, which included a long black funeral veil and revealed skin only at the ankles. She was also sporting a much more modest pair of shoes than she normally wears as part of her everyday outfits.

The Mother Monster recently spoke about how she feels how being in the spotlight of fame has made her feel "f*ck*ng old."

"I have been in the business since I was 15, and although I have been famous for only seven years and lived 29, I feel like I have lived 100 years," Gaga told news.com.au.

Even though the singer hasn't done much acting in the past, she says she was prepared to take on the role, since she's been studying method acting for about ten years.

"Arguably, it's the most dangerous form of acting where you embrace becoming the character and you embrace calling upon memory sensory from your life," she said. "It's powerful and it takes you back implicitly to a place that you remember as a child. It's very strong."

This is the singer's first-ever reoccurring acting role for a TV series. She previously made cameo appearances in the 2013 film "Machete Kills" and 2014 film "Sin City: A Dame to Kill For."

Gaga made her debut on "American Horror Story: Hotel," which was created by Ryan Murphy and Brad Falchuk, on Wednesday, Oct. 7.

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