Jack Osbourne Reveals What He's Learned About Marriage, Launches New M.S. Web Series

— -- Jack Osbourne has learned a thing or two about marriage.

He and his wife, Lisa Stelly, have been through a lot together from the start. Months before they walked down the aisle in 2012 and only two weeks after their daughter, Pearl Clementine, was born, the son of Ozzy and Sharon Osbourne was diagnosed with multiple sclerosis. A year later, the couple endured a late-term miscarriage.

"I think as a society, we do families and marriage wrong completely," Osbourne, 30, told ABC News.

"Listen, marriage it’s a moving target all the time. It's two people deciding to live together, have a family together and function as a unit," he continued. "But there’s so many individuals and so it’s [about] always being able to work together as individuals and accept certain shortcomings and adapt to others."

Osbourne has also learned from his parents' marriage. Ozzy, 67, and Sharon Osbourne, 64, briefly split this year before reconciling.

"You can’t just be complacent in marriage and be like, 'This is it! The end,'" Osbourne said.

"Lisa and I we put a lot of work into our relationship and we really try to look at the bigger picture," he continued. "Whether we’re in a fight with each other and we’re like, 'Screw you, F you, I’m calling the lawyers!' And then it’s like, 'Alright, I’ll get over it. We’ve got kids to worry about.'"

Osbourne credits his wife with helping him flourish despite his M.S. diagnosis. He recently launched a new web series titled, "You Don't Know Jack About M.S.," to raise awareness about the disease.

The reality star said he thought it necessary to help inform the public after being "fired from a production or basically 'unhired' because they deemed me not able-bodied."

"They were like, 'Oh, he can’t physically do it ... and I got really frustrated because M.S. is super unique and it’s different with everyone," he explained.

Osbourne was diagnosed in 2012 after his legs went numb. He also suffered temporary blindness in one eye, he told ABC News.

Today, Osbourne said he manages his M.S. by taking an injectable medication three times a week. He also has changed his lifestyle by eating healthily, exercising and maximizing his rest.

"There’s nothing I can’t do," he boasted. "I think probably having kids stops me from doing more things than M.S."

"I’m lucky though; that’s not the case with everyone, and it’s partly the reason why I started 'You Don’t Know Jack About M.S.' with Teva Neuroscience," Osbourne continued. "[It] was to kind of really explain to people what M.S. is, how it affects people, how it doesn't and how different it is with everyone."
