Katy Perry's Parents Go Silent About Tell-All Book

Last week, we heard that Katy Perry’s mother is currently shopping around a book that talks about how Katy “has impacted her Christian ministry.”
Now, Katy’s parents have gone silent on the subject, refusing to give out new deets about the book to anyone.
Here’s what Katy’s father Keith Hudson had to say about it:

├óΓé¼┼ôWe have been inundated with calls on this subject and we are not going to comment on any book release.”
“That’s all we have to say on this topic at the moment.”

Why so quiet about the book, you two? More details would be appreciated!
