Jack Osbourne Diagnosed With Multiple Sclerosis

Just a few weeks after enjoying first-time fatherhood with fiancee Lisa Stelly, Jack Osbourne has received some devastating news.

The son of Ozzy and Sharon Osbourne reveled to People magazine that he has been diagnosed with multiple sclerosis. The disease attacks the central nervous system, affecting the brain, spinal cord and optic nerves.

"I was just angry and frustrated and kept thinking, 'Why now?' the 26-year-old Osbourne told People in an exclusive interview that also included his mother Sharon. "I've got a family and that's what's supposed to be the most important thing."
