Bradley Cooper was honored with the Sid Grauman Award at the American Cinematheque Gala on Thursday (Nov. 29), and Lady Gaga got teary-eyed during her emotional speech presenting her A Star Is Born co-star with the award.

“When we do these Q&As and things together, sometimes you call me Gaga, but we both know that you call me Stefani,” she said emotionally. “I ran from Stefani for a long time, and I put on a superhero cape and called myself Lady Gaga. He challenged me to deep dive into a place where I had to see her again. Where I had to be Stefani again.”

“I’m so grateful to you, not just for making me a better actress,” she continued. “But I’m so grateful that, not have I only been able to call you as a professional, but I’ve been able to call on you as a friend. To cry and be myself, and have you never, ever judge me and still respect me as a professional. Thank you for that.”

Gaga also compared the actor and director to "legend" Tony Bennett, who she collaborated with on their 2014 album, Cheek to Cheek. Watch her full speech below.
