Breakout is the second studio album (third overall) by American teen pop singer Miley Cyrus. It was released under Hollywood Records on July 22, 2008 in the United States and debuted #1 on US Billboard 200 chart with first week sales of about 371,000 copies.

Breakout is the first album by Miley Cyrus that does not have any affiliation to the Hannah Montana character. Cyrus has said that Meet Miley Cyrus was "just meeting me, finding out who I am", while Breakout was inspired by "what's been going on in my life in the past year."
"I wanted to embrace my older audience a little more, kind of taking shackles off and doing the music I wanted to do," Cyrus said of Breakout. Cyrus co-wrote all songs on the album apart from four. "Songwriting is what I really want to do with my life forever, [...] I just hope this record showcases that, more than anything, I'm a writer." A majority of the songs are co-written by Antonina Armato and Tim James, the writers of "See You Again" and "Good and Broken".

Two of the four songs that Cyrus did not co-write are covers. "These Four Walls" was originally recorded by MTV reality TV star Cheyenne Kimball, who released it under the song title, "Four Walls"; the song had appeared on her debut album The Day Has Come. Coincidentally, Kimball also has a song titled "Full Circle", but Cyrus's song of the same name is an original composition. Cyrus also covered Cyndi Lauper's "Girls Just Wanna Have Fun". The song was originally performed by Miley with the The Cheetah Girls on their Party's Just Begun Tour. Cyrus recorded it as a solo song when it didn't appear on the Cheetah Girls' debut album TCG. The album's title track was written by Gina Schock of the Go-Go's, Ted Bruner and Trey Vittetoe. The title track was initially sung by Katy Perry, who also provides background vocals on that song as well as "The Driveway".[citation needed] "Simple Song" is the only other song that does not feature a writing credit from Cyrus.
