Kelly Osbourne is an English television personality, singer, award winning actress, radio presenter and fashion designer. She is the daughter of Ozzy and Sharon Osbourne Kelly first rose to fame in The Osbournes, the Emmy-winning reality TV series about her famous father and his family.

Kelly Osbourne was born in the City of Westminster, London, the middle child of Sharon and Ozzy Osbourne, the others being her older sister Aimee and her younger brother Jack. She also has two half-siblings: Jessica Hobbs and Louis John Osbourne from Ozzy's first marriage. She also had an unofficially "adopted" brother, Robert Marcato, who Sharon and Ozzy adopted after Marcato's mother died. Kelly grew up traveling with her father as he went on tour, and lived in more than 20 homes.

Kelly Osbourne and the rest of her immediate family (without Aimee) were thrust into the international spotlight with the MTV reality show The Osbournes. It chronicled their day-to-day life, and the show became a runaway hit for its portrayal of a dysfunctional, though close-knit, family where metal music, profanity and other harshness were a daily part of life.

Her debut album, Shut Up!, was released in 2002 to moderate sales, fueled mostly by a cover version of the hit Madonna song "Papa Don't Preach", which was debuted with Houston rock band Pure Rubbish at the 2002 MTV Movie Awards. "Shut Up!" debuted at #1 on Billboard's Heatseekers chart. The album was met with bad critical reviews and, by May 2003, Osbourne had been dropped from Epic Records. However, by autumn she had resurfaced on the Sanctuary label, later recording a duet of "Changes" (a Black Sabbath song) with her father. The duet hit #1 on the UK charts, a first for both father of the Billboard charts to top all three dance surveys in the same week.

Osbourne made her debut as an actress with a starring role on 7 October 2004 on the Abchigh school teen drama Life As We Know It, where she played the supporting role of Deborah Beatrice Tynan. In June 2006, Osbourne played the role of Wendy from Peter Pan in The Queen's Handbag. In 2006, Osbourne provided a voice for the animated film Live Freaky Die Freaky. In July 2007, it was announced Osbourne was to take on the role of prison matron Mama Morton in the musical drama Chicago. Her seven-week run (from 10 September) in the musical at the Cambridge Theatre would be her stage debut. She won the Glamour Award for Theatre Actress of the Year.

Since her rise to fame, Osbourne has been called on to present for various events. Osbourne co-hosted the 2006 edition of I'm a Celebrity... Get Me out of Here! Now, a spin-off show of the main ITV1 program. She hosted alongside Jeff Brazier in Australia, and Mark Durden-Smith in the London studio.

In Spring 2008, she began contributing a Teenage advice Column to the Tabloid Newspaper The Sun, “Kelly Confidential”, where she is billed as the teen trouble shooter.

After her appearance on the reality show, Osbourne quickly began to be noted for her varied and trendy style among fashion commentators like Steven Cojocaru. In 2004, Osbourne launched her own fashion line, Stiletto Killers, with friend Ali Barone. Stiletto Killers was a rock-inspired line of tees, knickers, hoodies, and sweatpants designed by Osbourne and Barone, emblazoned with cartoonish designs and punk rock phrases. There was also a more sophisticated couture branch, The SK Collection. Stiletto Killers closed in April 2006 and Barone has since launched a line called Lipstick Prophets.
