The upcoming film "Charming" will include the voices of Disney alums Ashley Tisdale and Demi Lovato, as well as Avril Lavigne and Chinese singer G.E.M.

The film will include an original script by director Ross Venokur, which tells the comedic story of how popular Disney princesses, Cinderella, Snow White and Sleeping Beauty, find out that they are all engaged to Prince Charming.

Earlier this year, Lovato was announced to voice the lead character Lenore by The Hollywood Reporter.

"3QU Media's goal is to produce mainstream animated family films with elements of comedy, adventure, romance and personal inspiration," said the film's producer, John H. Williams. "Demi's contributions will help make 'Charming' a cross-platform hit film."

Lovato will not only be voicing the lead role, but will also be the executive producer for the film's music score.

"Demi, Avril, Ashley and G.E.M. are among the most popular young stars in the global entertainment arena," said Williams in a statement on Wednesday, reported Billboard.

Lovato and Tisdale both have a large youthful following, which began on Disney Channel. Tisdale appeared on "The Suite Life of Zack and Cody" for three years and went on to appear in the "High School Musical" franchise. Lovato, who is currently on the Billboard charts with her latest hit "Cool for the Summer," appeared in two "Camp Rock" films, the hit show "Sonny with a Chance" and "Princess Protection Program" with Selena Gomez.

For Lavigne, this project is part of her comeback. The singer recently performed at the Special Olympics Opening Ceremony and spoke about her battle with Lyme Disease.

"Honestly, I felt very, very loved," she said, reported E! Online. "And it sounds silly saying it, but I really truly did feel my fans through the process. For me, it's like a second shot at life. I really just want to go out there and truly do what I love so I'm so excited for life after this.
