The 26-year-old star has revealed she would love to have a conversation with Gaga, 28, to get an insight into how her mind works, reported the Daily Star.
"I've seen her live a few times, and every time she does the jazz solo, just her and her voice and the piano.
"I'd love to work with her just to see how she thinks. To have that much independence and confidence about being so far away from the normality of what people expect; it's very dreamy," Jessie said.
"It's really interesting and admirable. I'd love to just have a conversation with her and see what goes through her head," she added.
