Hilton served 23 days of a 45-day jail sentence in June for violating probation on a 2006 drunk-driving charge.

But her literary agent Dan Strone insists her spell in jail will not be the focus of her third book.

He says, "She is planning to do another book. She is thinking of doing a new book, and I don't believe at this time, it's contemplated to be a so-called prison diary. I don't think that's the direction she's heading."
