Jack Osbourne opens up about MS diagnosis
Ozzy Osbourne's son Jack appears on US daytime chatshow The Talk, co-hosted by his mother Sharon, to talk about his recent diagnosis with multiple sclerosis.
The 26-year-old television presenter and former reality TV star was given a rousing cheer as he entered the studio led by the hand by his mother.
Despite telling the audience he felt "fine", Osbourne said he had learned MS "is a completely unpredictable disease."
The young father first went public with the news of his health in an interview with People magazine.
He told People he realised something was wrong just last month after losing his vision in one eye.
On The Talk, which was broadcast on Wednesday, Osbourne said his sight had returned "about 80 per cent" and doctors "don't know if it will ever improve beyond that."
Multiple sclerosis attacks the brain and spinal cord, and can cause mild problems or serious disability, such as paralysis.
The former reality star became a father to his first child in April. He and fiancée Lisa Stelly welcomed daughter Pearl in April.
Osbourne gained fame as a teenager when his heavy metal musician father and his mother allowed the family to be profiled in the MTV reality show The Osbournes.
