During Elton John's 20th Annual Race To Erase MS Benefit Friday night, Osbourne, who was there with wife Lisa Stelly, told E! News how he's been dealing with his diagnosis.
"When I got diagnosed, the more research I did about it—MS overall, as a subject, as a disease—there's a lot of misconceptions and there's a lot of unknowns about it, and there wasn't anyone out that was close to my age or close to anything like me out there" he told us.
"And I'm not saying I was trying to be the hero and wave the flag, but I was like, 'Why don't more people know about this?'"
Osbourne continued to share that, "It's not a disease of age, a lot of people think it's for women in their 40s, most commonly, because that is the most common diagnosis, but it's not. The youngest diagnosis has been of a 3-year-old. So this is a disease that affects everyone differently, much like a fingerprint. It's unique to every single person who has it and that's what makes it so tough."
Kelly Osbourne's brother admits he's had a lot of people reach out to him over social media about the disease, and although it's a kind gesture, that's not the reason behind his motive to learn more about MS.
He told us, "I do it for the global cause of like, 'There has to be a solution to this.'"
