Kelly Osbourne

Reality TV kid – and upcoming contestant on "Dancing With the Stars" – Kelly Osbourne was in Dublin last week signing copies of the new book she wrote about herself called "Fierce."

What could a 23-year-old possibly have to offer the world in book form?

Well, as the youngest child of Sharon and Ozzy she’s certainly led a crazy life, one that’s already been filled with drug addiction, weight problems and lots of self-loathing. Her book, she says, is an attempt to “help” other ordinary folks going through the same things.

She also offers advice on make-up, fashion and how to make it in the music industry.

The “expert” she consults about music is Irishman Louis Walsh, who’s a judge with Simon Cowell on the huge British show "The X Factor," the "American Idol" elder sibling.
