Singer Kelly Osbourne has ruled out following in the footsteps of her brother JACK BY writing an autobiography, because she doesn't have enough stories to fill the pages. The 22-year-old daughter of Ozzy Osbourne admits she doesn't have as much to write about as younger sibling Jack, who filled his book 21 YEARS GONE: THE AUTOBIOGRAPHY with revelations about beating his drug and alcohol addictions and his 70 pound (31.8 kilogram) weight loss. Kelly says, "If I was to write a book, it would be two f**king chapters long. I'm only 22. "Jack had something to write about because he had a dramatic life change. I haven't lived long enough to write a book."
