Lady Gaga says she was surprised by her fiancé Taylor Kinney's reaction to her making an acting debut on American Horror Story: Hotel, which premieres tomorrow on FX.

"What guy in that scenario would be like, 'Sure, babe, do TV!'?" Gaga told E!. "He does TV, that's his thing. I do music, and you know, we're together. But I sort of was like, 'Is it cool if I do TV?,' And he was like, 'F--k yeah!'"

Gaga adds that Taylor has been "exponentially supportive the entire time and just like, so cool" as she prepared for her role on the Emmy-winning series.

She recalled: "He was like, 'We can read scripts together, and we can talk about our characters together, and I can teach you how to be on set! And he taught me all about etiquette and what actors would appreciate during their coverage. He taught me to make sure that I was always available fully to the actors when I was working so that when the coverage is on them that I don't drop my character, that I'm always in it for them, and you know, that's invaluable advice."

American Horror Story: Hotel premieres tomorrow at 10 p.m. on FX.
