Sharon Osbourne says her son Jack is holding up well after he was recently diagnosed with multiple sclerosis.

Through tears, Osbourne discussed her son's diagnosis Monday on her CBS daytime program The Talk . She said, "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."

Osbourne added that the public's well wishes have been "amazing for Jack 'cause I really believe that vibes of prayer help."

Jack, 26, echoed that sentiment on Twitter over the weekend, writing , "Thank you all so much for the kind and inspirational words. It means a lot. #adaptandovercome."

Sharon and Ozzy Osbourne 's son welcomed a daughter with his fiancée, Lisa Stelly , in April. He is scheduled to appear on The Talk on Wednesday.
