The son of Ozzy and Sharon scouts out new talent for Epic Records. He
also has influence on what bands appear on Ozzfest. He can be found
on cd covers being thanked for helping rising bands.
Jack's favourite band is Tool, which is reflected in the t-shirts he
often wears. Rumors circulate that Jack is gay, Jack has said that he
once had sex with three women at the same time which would prove
otherwise if he's to be believed. He's been seen with Rod Stewart's
daughter Kimberly and model Catalina Guirado. It's been reported that
Jack has been helping her launch a pop career in LA and the pair have been
seen on dates. He's writing songs for her.
He appeared on Dawson's Creek as a cameo appearance as well as That
70's Show in 1998.
Jack has a bit of a weight problem as does his sister Kelly. This
seems to be a much debated topic on the internet.
