"Honestly, I'm fine," Osbourne, 26, said when asked how he's doing. He said the unpredictability is the toughest thing about the the autoimmune disease, which affects the brain and spinal cord. Symptoms can vary, ranging from loss of balance to problems with coordination.

Osbourne has had symptoms for the last three or so years, but had no idea what it was until doctors diagnosed him only five weeks ago.

He had problems with his bladder and stomach, and about two years ago, Osbourne's legs felt "numb" and "tingly" for about two months.

He then lost a good part of his vision, which he says is now back to 80 percent.

A new father, Osbourne said he hasn't had time to get too upset about the diagnosis. He and his fiancee, Lisa Stelly, are busy with their newborn, which Osbourne says is a good thing. The couple welcomed daughter, Pearl, in April.

The son of rocker Ozzy Osbourne also told the women of "The Talk" that he's taking a "middle of the road" approach in terms of treatment, combining prescription medication with overall life changes.

Lisa, who also appeared on the show Wednesday, said, "He's going to have to change his diet. He's going to have exercise more ... it could actually be a good thing," later adding, "He's going to be OK."

Having only been diagnosed a little over a month ago, Osbourne says he's still learning about MS. But he definitely wants to help educate others.

"So much little is known about it, so that's one of the reasons I want be somewhat vocal about it," Osbourne said.
