The singer admitted that she has a "girl crush" on the star and hopes to be introduced to her soon.
Discussing Perry's movie Part Of Me with Digital Spy, she said: "I haven't [seen it] yet but I really want to!
"I really fancy Katy Perry - she's definitely my girl crush. She's so talented and I'd love to meet her one day."
The 17-year-old also revealed that her forthcoming album has more than the "rock chick" sound she portrayed as a contestant on The X Factor, adding: "Everyone was predicting that kind of sound and I think I've come out with a song that's the opposite of what people expect.
"That's what I love about it! I don't want to be the next Pink or Kelly Clarkson, I want to be Amelia Lily. 'You Bring Me Joy' represents all the different sounds that I love and my passion for it all."
