The photo of seven-year-old Ali with her mother is a photo of a much younger Christina Aguilera with her mother, Shelly Kearns.
Most of the flamboyant costumes worn by Cher were her own clothes, some of which were designed by her longtime friend Bob Mackie (interview on The Graham Norton Show (2007) / 18 Dec. 2010).
Steve Antin got the idea for this film after watching Christina Aguilera perform as a featured vocalist for The Pussycat Dolls in 2002. He is the brother of the group's creator, Robin Antin.
