Jack Osbourne, son of heavy metal icon Ozzy Osbourne and TV personality Sharon Osbourne, first caught America's attention on the hit reality show "The Osbournes."
Now he's a TV and film producer whose latest ventures include a historical road trip with his father, and a clothing line for dads.
Jack also lives with relapsing-remitting Multiple Sclerosis, and is raising awareness through a series of webisodes in the campaign called "You Don't Know Jack about MS."
Jack Osbourne joined us on KTVU the 9.
