Ozzy Osbourne's son Jack will be following in the footsteps of his sister Kelly, when he appears on "Dancing With the Stars", as a celebrity competitor.

As far as the celebrity part, Jack may be more well known for his role in raising awareness for Multiple Sclerosis (MS), something he also intends to do while on the show.

“Having been diagnosed with MS and going through that whole roller coaster, I saw it as an opportunity, almost a greater responsibility to keep MS awareness on people’s minds,” Jack tells USA Today. “Although there is treatment for it, we’re no closer to a cure. I’m trying to raise awareness that way.”

Jack will be paired with dance pro Cheryl Burke.  Competition includes Leah Remini from "Kings of Queens", former NFL player Keyshawn Johnson, and "Jersey Shore's" Snooki.  The season premiere is September 16.
