Ozzy’s son, Jack Osbourne has been diagnosed with multiple sclerosis.
Jack is only 26 and learned of his illness two weeks after the birth of his first daughter Pearl with his fiancée Lisa Stelly.
The often fatal disease affects the central nervous system and can cause problems with muscle control, strength and stamina.
Kelly Osbourne tweeted,
“please support my brother in not only his bravery but honesty!”
