"The Talk" co-host announced that her 26-year-old son would make an appearance on the show on Wednesday to talk about his diagnosis himself.

She continued thanking those who have reached out to her family and given them words of encouragement.

"Just thank you to everyone, for all their good wishes it's been amazing, but for Jack cause I really believe that vibes of prayer help," she said.

Jack Osbourne revealed his heath crisis in an interview with People magazine on Sunday. He told the publication he received the diagnosis just two weeks after the April 25 birth of his daughter, Pearl Clementine.

Multiple sclerosis attacks the brain and spinal cord, and can cause somewhat mild problems or serious disability, such as paralysis.
