Her family has definitely experienced plenty of drama over the years, however Kelly Osbourne says her brother Jack Osbourne's battle with multiple sclerosis is going quite well.

The “Fashion Police” star noted that she often forgets that her sibling is even afflicted with the illness. “He’s amazing. He’s unstoppable. It’s like it’s not even there.”

She continued, “He always reminds me that it’s not just him that we’re fighting this race for. It’s the 2.1 million people living with it as well.”

"I've done a T-shirt campaign for Race to Erase MS. I've been going to events for years, and especially since my brother was diagnosed … I've so wanted to be a part of the charity."
