The youngest child of heavy metal icon Ozzy Osbourne and talent manager/TV personality Sharon Osbourne, Jack first caught America's attention on the hit reality show "The Osbournes," which followed the adventures of Jack and his family. As the show concluded, Jack went on to star in "Jack Osbourne: Adrenaline Junkie." He emerged looking like a new person — gone was the thick curly hair, along with 70 pounds of body weight.
Over the next four years, Jack starred in the series "Jack Osbourne: Adrenaline Junkie," and more recently, he ambitiously took on producer and director roles. He produced a documentary about his father, "God Bless Ozzy Osbourne," which premiered in 2011 at the Tribeca Film Festival, and directed a music video for Ozzy's song, "Life Won't Wait." Jack is currently producing film and television through his production company Schweet Entertainment, including the docu-series You Don't Know Jack About MSTM, in partnership with Teva Neuroscience, Inc.
Jack and his wife, Lisa Osbourne, have a daughter, Pearl, who was born in 2012, just two weeks before he was diagnosed with relapsing-remitting multiple sclerosis (RRMS), the most common form of multiple sclerosis (MS). Since his diagnosis, Jack has worked as a passionate MS advocate, speaking out about the need for MS research and greater awareness. He was recently honored at Nancy Davis' 20th annual Race to Erase MS Gala for his courage in announcing his diagnosis, as well as for acting as a role model to others who suffer from MS. He plans to start a foundation to help raise money for MS research.
