Whitney Houston and Brandy chatted with ET on the set of ‘Cinderella,’ allowing us to share these intimate behind-the-scenes moments, even from the recording studio as they sang their iconic duet, ‘Impossible’! Houston shared the story of when she called the 18-year-old singer to offer her the lead role, and revealed how she was like Brandy’s fairy godmother in real-life. ET captured Brandy’s jaw-dropping reaction the first time she walked onto the incredible movie set that caused her to exclaim, ‘This has gotta go in Disneyland!’ Brandy later had a true Disney princess moment at the premiere when she made her grand arrival in a horse carriage on Hollywood Boulevard. Houston told ET after the movie that she was ‘so proud’ of Brandy’s performance. And how about this for a fairytale ending: ‘Cinderella’ comes to Disney+ on Feb. 12. Everything, indeed, starts with a wish!
