Jack Osbourne says that he will "overcome" his fight with autoimmune disease multiple sclerosis.

The 26-year-old son of Ozzy and Sharon Osbourne announced last month that he had been diagnosed with the illness just as he became a father to his first daughter, Pearl.

But the reality star told Good Morning America today that he will "adapt [to] and overcome" his battle and after losing 80 percent of his vision, he was starting to see improvement.

"[My] vision is coming back slowly," he revealed adding that he had the "most common and least aggressive" strain of MS.

"It's kind of manageable," Jack shared. "I've stared medication, my vision's coming back slowly other than that, no side effects."

Jack also revealed that he has had to change his life to a new "recipe for good living" which included eating well, getting good sleep and eliminating stress from his life.

He also credited talk show host Montel Williams as his "go-to-guy" for any queries he has about the illness.
