Jack Osbourne Debuts Baby Pearl

Jack explained, "People say when you have a kid it’s like instant love, but unless you've experienced it, it's impossible to comprehend."

Osbourne also confessed that he was shocked when he found out that Lisa was pregnant just three months after they met. "I think I responded with 'That's interesting.’ What do you say? If we'd been trying for two years, of course you'd be like 'Awesome!' But we met in May and found out in August.

After calling his old nanny, Jack shared, “I just said, 'S*** What do I do? She talked me off the ledge.”

And Sharon couldn’t be happier to be a grandmother. "It’s incredible to see Jack holding his baby girl, walking around so confidently . . .He's very nurturing and he and Lisa are so good together."
