She told Digital Spy, "You know what? I have to see it as naive and lazy comparisons.

"My face has been the same since I was born, but as soon as I had a bob, my music sounded like Katy Perry's. Now I've got short blonde hair, my music all of a sudden sounds like Miley's and Pink's. It's young people a lot of the time, because they're very obsessed with one person.

"It used to bother me, but it doesn't anymore. I know what makes me different. The lyrics of mine and Miley's are similar, but the songs are completely different. You'd never seen me kissing a doll in a swimming pool!"

She added, "She [Cyrus] pulls it off, but I couldn't."

Jessie J's new album Alive will be released on Monday, September 23rd.
