Pop star Kelly Osbourne has signed a new deal to pen a teen advice book. Ozzy Osbourne's former wild-child daughter, who quit school early and fought drug addiction through her teenage years, will write Fierce as a guide for troubled adolescents.

She tells WWD.com, "It’s about all the major things girls go through before they turn 21... It's 16 chapters where I explain what I did and where I went wrong, and then I offer professional advice on how to do things differently."

Now 24, Osbourne underwent rehab in Malibu, California in 2004 in a bid to kick an addiction to painkillers. A year later, she checked into a drug treatment center in Pasadena, California following a relapse.

She reportedly entered another drug treatment facility in January after suffering another relapse.
