Jack Osbourne has opened up about his diagnosis with multiple sclerosis.
The 27-year-old welled up on an episode of Dancing With The Stars, as part of the show's Most Memorable Year theme, reported Digital Spy.
He said 2012 started off well when he moved into a new house with his now-wife Lisa, followed by the birth of his daughter in April.
"Becoming a father is the most daunting but liberating, electrifying moment," he said.
"Pearl was born and then barely two-and-a-half weeks later I was diagnosed with MS. You now have this disease that there's no known cure for, and if it gets bad the remainder of your years could be spent in a wheelchair with feeding tubes."
Jack continued: "It was scary, but I wasn't so much scared for myself - I was scared for my kid.
"Because it's like, you have a kid. Your whole thing is like, 'This is my kid, and I have to care for it, and now I'm going to be in a f***ing wheelchair'.
"I don't care what happens to me, if it's just me. But if my quality of life goes to a place where I can't provide for a kid, my whole thing was like, 'F***, what is this?'."
According to Digital Spy, Jack said he had "four days of just feeling really down and depressed" but that having a three-week-old baby helped him think about other things.
"I don't know how I would have dealt with this if I didn't have Lisa or my kid at the time. If you don't have bad, you can't appreciate good," he said.
"I really think having gone through some of those really bad moments made me realise how special these special moments are."
