"She definitely wanted me to continue on to, you know, represent us as a group," Pointer said of her sister. "And I'm here at her beautiful home in Beverly Hills now and hanging out with her, and me and her and her granddaughter Roxie and a friend Melissa watched it together last night and just screamed our heads off."

After revealing their identities, competitors often comment on how difficult it is to perform in their elaborate costumes.

"You know those wardrobe boxes that you use to pack? If you're going to, if you can imagine singing with that on your head you kind of know what I felt like," she explained.
