The newest Prince Charming-centric pic has found its array of musicians, and the line-up is its most ... eclectic to-date.

InStyle caught up with Chinese pop singer Gloria Tang Shi-Wing (G.E.M.) to discuss, among other things, her part in the upcoming film, and she revealed that not only will she be voicing Sleeping Beauty for the pic, but she'll also be teaming up with Avril Lavigne, Demi Lovato, and Ashley Tisdale to sing a Fall Out Boy-written song for it. Yep.

"Charming," which is now expected to hit theaters in 2016, will feature Ashley Tisdale as Cinderella opposite Wilmer Valderamma's central Prince Charming. Meanwhile, Lavigne will lend her vocals as Snow White, and Lovato will voice a character named Lenore.

This is going to be something ELSE, guys.

For her part, G.E.M. says she's "quite nervous" about recording the song for the pic because it's her first English tune. Even so, "the whole experience is phenomenal," she told the mag.

While Fall Out Boy might seem like a surprising choice for animated film songwriting, they're actually going to be featured on the star-studded We Love Disney cover collection with a rendition of "The Jungle Book" feel-good anthem, "I Wanna Be Like You (The Monkey Song)," which they told the AP they picked because "there's something kind of dangerous and punk rock about the way King Louie is in the song, in the film. He's kind of a villain, but kind of not -- just kind of out for himself. There's something weirdly relatable about that."

Perhaps that same logic will apply to their number about the shoe-searching monarch in this movie?
