Idina Menzel sang Camila Cabello's praises in an interview with Insider about their upcoming movie "Cinderella."

Menzel was speaking to Insider as part of her collaboration with Rice Krispies Treats to launch their new "365 Days of Love and Support Kits" designed to encourage parents to share daily encouragement with their children.

She stars in the musical remake of "Cinderella" as the wicked stepmother whilst Cabello plays the titular character.

This is the first movie role for the pop star known for hits such as "Havana" and "Senorita." Menzel told Insider that Cabello was a "rockstar" whilst filming "Cinderella."

"I think that she's super talented." Menzel said. "She's funny and open and down to earth and plays a character with beautiful imperfections and she was just a joy to be on set with."

The 50-year-old Tony Award winner continued: "She allowed herself to be open and vulnerable and we really hit it off. I always admired seeing young people that really know a sense of who they are and yet are not afraid to show their vulnerability. So I respect that so much."

"Cinderella" will be released on Amazon Prime on September 3rd and features other stars such as Billy Porter, Pierce Brosnan, and James Corden. Whilst most of the songs within the movie will be covers, Menzel told Insider that there are two originals in the movie, one sung by Cabello and one sung by herself.

Menzel said it was a "real milestone" to shoot her song, "Dream, Girl" because she had co-written it with songwriter Laura Veltz.

Menzel said: "A lot of people submitted songs for this moment in the movie and I went with my friend, Laura Veltz and we co-wrote a song. I submitted it not knowing if Kay [Cannon, the director of 'Cinderella'] and she embraced it."
