Sharon Rachel Osbourne is an English and American television personality, businesswoman and author. She came to prominence while appearing on The Osbournes (2002–2005), a reality television show that aired on MTV, which followed her family's daily life. Osbourne later became a judge on television talent competition shows, including The X Factor (2004–2007, 2013, 2016–2017) and America's Got Talent (2007–2012).
Osbourne was married to heavy metal singer Ozzy Osbourne from 1982 until his death in 2025. She is credited with reviving her husband's heavy metal career by founding the summer Ozzfest tour, which was held almost annually between 1996 and 2018. In light of her success managing her husband, she branched out into managing other acts, such as Gary Moore, Motörhead, Lita Ford, The Quireboys and The Smashing Pumpkins, through her company Sharon Osbourne Management. From 2003 to 2004, Osbourne hosted her own television talk show The Sharon Osbourne Show, which was syndicated to various American channels and also shown in the UK on Sky One.
