"The Best of Both Worlds" is a pop-rock song performed by American singer and actress Miley Cyrus for the Disney Channel television series Hannah Montana.

Cyrus performs the song as Hannah Montana, who is the alter ego of the series' protagonist Miley Stewart.

"The Best of Both Worlds" is a song with influences from dance, rock and country music,[2][3] and its instrumentation features offbeat electric guitars, upbeat synths and backing vocals.

Lyrically, the song is one of several songs ("Just Like You", "The Other Side of Me", "Old Blue Jeans", "Ordinary Girl" and "Rock Star") that explicitly allude to Stewart's double life as Montana: regular adolescent that moved from Nashville, Tennessee to Malibu, California by day and pop star by night.

[2] In the song, Cyrus sings about the privileges and advantages that are faced in leading in two lives, with references to Orlando Bloom, concerts, friendship and film premieres.

[2] Chris Willman of Entertainment Weekly compared the song to the musical styles of Avril Lavigne, Ashlee Simpson and Britney Spears.

[5] However, Willman stated that the concept of "The Best of Both Worlds" was "a nice fantasy for Brangelina, but a weird one to push on little girls".

[12] Cyrus often dressed as the Hannah Montana character when she performed "The Best of Both Worlds" at concerts and promotional television appearances.

At the concert taping to promote the first season of Hannah Montana, Cyrus dressed in boots, jeans, a pink-sequinned blouse, khaki jacket, and blonde wig,[13] to perform "The Best of Both Worlds" and five other songs.

She performed the song as herself, wearing an all-pink outfit composed of a tank top, plaid mini-skirt, sneakers, and a jacket.
