Mariah Carey is having  a great and powerful moment…

The 42-year-old half-Afro-Venezuelan singer has released the official music video for her latest single “Almost Home,” the theme song for the film Oz: The Great and Powerful.

Recorded by the American Idol judge for the Sam Raimi-directed film, which opened this weekend, the “feel-good record” was co-written by Carey.

The clip, directed by David LaChapelle, captures the singer belting out the song alone, while dressed in a black gown. The photographer-director intersperses footage from the Disney adventure fantasy film throughout the 3 1/2-minute clip.

“I’ve always just loved Disney, and now especially having two little babies – like all we do is watch animated movies, even though they’re so little, they still love them, especially Roc, my little boy,” said Carey, revealing how her twins Moroccan and Monroe had inspired her to write the song.

Carey is currently in the studio working on her next album, which is due in May. The album will include production by Jermaine Dupri, Bryan-Michael Cox, Big Jim Wright, Hit-Boy, The-Dream, Rodney Jerkins and contain a “lot more raw ballads than people might expect,” says the singer.
