Katy Perry's breast flaunting traumatises her mother!

Katy Perry's mother Mary Perry Hudson has revealed that she feels ashamed when she sees her daughter flaunting her breasts.

Katy Perry's Teenage Dream is a middle-aged nightmare for her evangelistic mom - who complains in a book that, "no mother wants to see the top of her daughter's breasts," reports the New York Post.

Preacher Mary describes her horror when she saw Katy's outfits at a concert, "Katy stepped out from behind the changing doors in a tiny risque costume. No mother wants to see the top of her daughter's breasts.

"My first instinct was to order her back behind those doors and demand she put something else on . . . However, I had no problem letting my eyebrows say what I wouldn't allow my mouth to utter," she further wrote.
