“I’ve loved her from afar,” Sam Elliott told Glenn Close during Variety‘s Actors on Actors about working with Lady Gaga in “A Star Is Born.” “She was just kind of this regular girl on some level, this Stefanie,” he said, noting that he always called her by her first name, not her stage name. “She was stunning to work with.”

He remembers one day during the filming of the live concert scenes when Gaga jumped up on stage without warning.

“She just came out of nowhere and sat down at the piano and started singing,” he said of Gaga. “Everybody just stopped. It was just magical.”
