His wife-to-be has reportedly thrown out the book, which contained details of his past flings, to keep him from temptation.
When the Daily Record asked the singer if Brand still had it, she replied simply, "Not anymore."
Despite being separated while Brand films his new movie Arthur, Katy, 25, said she still manages to keep an eye on her beloved. She said, "Russell's good. He's in New York filming at the moment. The last picture I saw was of him in the bath, and Helen Mirren was giving him a wash. I think it's his dream come true.
"Russell and I do a lot of chatting through text and BlackBerry Messenger and sometimes he will send me pictures but there is a time difference. Then I get these pictures and I'll be like, 'What's going on? Why is Helen Mirren bathing you?'
"And I will get no response because he'll be asleep and I'll be freaking out."
