Jack Osbourne has described Ozzy Osbourne's final show as a "living wake"

Speaking on Good Morning America, Jack cried as he said: "Before he went onstage, I ran back into the dressing room, and I just gave him a big hug. I just kissed him.

"I was like, 'Crush it. You're gonna do so good.'

"And I was crying. I was in the crowd... There was this area in the crowd, and I was with my brother. And we both were just crying. Not because... It wasn't because of feeling sorry for him. It wasn't because we were sad for him. I think it was because we knew it was his last time.

"In hindsight, it kind of was a living wake if you think about it. He got to say goodbye to everyone,."

Jack admitted he and his family, particularly his mother Sharon Osbourne, were not prepared for the "outpour of love" that they received following Ozzy's death.

He said: "I know she feels the love [from the public], and that has been such a level that none of us could ever really... You know, I think every child sits there and has this thought about one day their parents won't be there, and what will that be like? It's just a part of being human. We just didn't think of it."

Asked how Sharon is coping with the loss of her beloved spouse, Jack said he tells people: "She's okay, but she's not okay."

Jack recently recalled how he was given the news his dad had passed away.

He said in a YouTube video "I woke up in Los Angeles to a knock on my house door at around 3.45 in the morning.

"Someone who has worked for my family for about 30 years now was knocking on my door and when I looked through my window and I saw it was him, I knew something bad had happened. I was informed that my father had passed."

Ozzy had been battling Parkinson's disease and suffered various other health issues, and his son was thankful that he was no longer "suffering".

Jack added: "So many thoughts, there was a level of like, 'Okay, he's not struggling. He's not suffering anymore, and that is something'.

"I wish he was still here, you know? I wish he was still with us all, but he was having a rough go and I think people saw that at the show."
