The 16-year-old hit the studio for a duet with her Hannah Montana: The Movie co-star Emily Osment after the pair bonded on the set of the film, through their love of the late Beatles legend.
Cyrus tells Moviefone.com, "I'm just a huge John Lennon fan. I studied him , and just watched the movie Chapter 27 (which depicts his murder).
"We (Cyrus and Emily Osment) did a duet of Imagine, in the studio."
Cyrus doesn't reveal if the duet will ever be released - but she insists fans shouldn't be surprised by her eclectic musical taste.
She adds, "I don't think the music you produce has to be the the music you listen to. I like singing pop music, and I like dancing. And you can't really dance a lot to . I like Nirvana. I really like Radiohead. I really love the Beatles."
