Lady Gaga Became Bradley Cooper's Drag Mother for A Star is Born

Bradley Cooper may have directed Lady Gaga in A Star is Born, but Mother Monster still had plenty to teach him in return -- specifically, drag. In the film, Cooper's character meets Gaga's Ally at a drag bar -- staffed by Shangela and Willam -- where she performs "'La Vie en Rose" with full Edith Edith Piaf eyebrows.

"It was so wonderful, Bradley's curiosity about drag makeup," Gaga told Vulture during an interview at the Toronto Film Festival. "I remember having a whole conversation with him about soaping the brow, how you get the eyebrow to stay down. You pat it with powder and then you can't see it. All of these little details."

"I would just ask [Gaga] tons of questions and listen back to it and try to take things and think How can we mold this? And we really loved the drag bar idea and I really wanted her to sing 'La Vie en Rose,'" Cooper added. "Once I met [Willam and Shangela] on set, the possibilities became endless of what we could do in this space. It was so exciting."

Cooper also talked about his first experience with drag, which was inspired by his Wet Hot American Summer co-sta Amy Poehler. "I do have to say -- I just thought of it -- one Halloween [with] Amy Poehler, I went in drag. I remember walking around New York City, and I was like Oh, I feel like a woman. But it was hard to find shoes that fit [size] 13. I needed more prep time. My friend had this incredible wig, so I just took her wig." Gaga corrected: "Snatched it."
