POPSUGAR was on the ground at the Saturday night premiere of American Horror Story: Hotel [1] in LA, and we got the whole cast talking about the show's newest and most exciting member: Lady Gaga [2]! That's right, while Gaga was heating things up with Taylor Kinney [3], we asked her costars what it's been like working with her on set. Matt Bomer couldn't help but gush during our interview with him [4], but he wasn't the only one with words of high praise! Watch the clip above to see just how well-loved she is.
