The Ramona And Beezus actress has admitted that she's "flattered" by the comparison, but insisted that she's only trying to be herself.
Speaking to Now, the 18-year-old said: "I was a guest on [Cyrus's] show three years ago. So I'm not sure where this [rumour] has come from.
"I'm flattered if people say I'm the new Miley, but I'm definitely not trying to be her. I'm just trying to be myself."
Ramona And Beezus is currently playing in US cinemas.
