Russell Brand has reportedly put a halt to the third instalment of his autobiography My Booky Wook because things are getting so serious between him and Jemima Khan.

The pair have been dating for around a year and have stayed tight-lipped about the relationship, but according to the Daily Mirror, Russell is not planning to extend his kiss-and-tell book series now that he is in love.

In 2012 he had announced that he was going to write another book in the series, which it looked like ex-wife Katy Perry would feature in, but now it seems she doesn't need to worry about him telling tales if the plans have been shelved.

He had previously said: "Every time I get into trouble or something happens I think, 'That's a chapter!' I've already got three or four."

Now, Russell is thought to be planning to write a political tome and a children's book instead, out of respect for Jemima.

In an appearance on pal Jonathan Ross's ITV talk show, Russell said of Jemima: "I am in a relationship which is unlike anything I have experienced before. I really love her. This is the happiest I've been in this human life."
