Jack Osbourne, the youngest of Ozzy Osbourne’s three children, has been diagnosed with multiple sclerosis. Osbourne, 26, and his fiancé Lisa Stelly just welcomed their daughter Pearl in April. He told People magazine he was “angry and frustrated and kept thinking, ‘Why now?’” Multiple Sclerosis is an autoimmune disease that affects the central nervous system—the brain and spinal cord—and can affect muscle control, strength, vision, balance, thinking and feeling. The reality star gained fame after sharing the screen with his family on MTV’s “The Osbournes” in 2002. He also appeared on his own reality show “Jack Osbourne: Adrenaline Junkie,” where he undertook various extreme sports around the world.
