Sharon Osbourne became visibly upset when trying to discuss her son's multiple sclerosis diagnosis on her television show "The Talk" on June 18.
Osbourne's son, Jack Osbourne, recently revealed he was diagnosed with the disease two weeks after welcoming his first child.
"He's great -- he's doing really, really good and I want to thank everyone for all their texts and goodwill and love they send to us," Sharon Osbourne said as she paused to regain her composure. Osbourne took a while to begin her statement as co-stars, who also seemed a bit choked up, tried to comfort her. The video from this segment can be seen below.
Jack Osbourne will appear on the show on Wednesday to talk about his diagnosis. The 26-year-old took to his official Twitter page to thank people for their support.
"Thank you all so much for the kind and inspirational words. It means a lot," he wrote to his followers on June 17.
Multiple Sclerosis is a disease which attacks the central nervous system, made up of the brain, spinal cord and optic nerves, according to the National Multiple Sclerosis Society. The progression of the disease varies from person to person and symptoms can range from mild numbness in the limbs to paralysis.
Celebrities who have been diagnosed with the disease in the past include comedian Richard Pryor, former mouseketeer and actress Annette Funicello, talk show host Montel Williams and actress Teri Garr.
Sharon Osbourne later added, "Just thank you to everyone for all their good wishes. It's been amazing for Jack 'cause I really believe that vibes of prayer help."
Jack Osbourne and his family starred in the MTV reality series "The Osbournes," which ran between 2002 and 2005 and depicted the family's wacky home life, as well as frequent squabbles between the Osbourne siblings.
Ozzy and Sharon Osbourne are also parents to a 29-year-old daughter, Aimee, who did not appear on the show.
Jack Osbourne's bundle of joy is the first grandchild for Sharon Osbourne. Her husband and his first wife, Thelma Riley, have a daughter and son together and they have two children each.
