Jack Osbourne is a dad!

It seems like just yesterday we were watching young Jack Osbourne chilling at home with his old man, Prince of Darkness, and his dogs just being a (wild) kid. Now Jack is celebrating the birth of a daughter with his lovely fiancee Lisa Stelly.

Hello got the exclusive from Jack and Lisa. Editor Rosie Nixon tweeted the good news, “Big congrats @MrJackO & @lisamarstelly who today welcomed baby Pearl into the world. She weighs 8lb6oz & all are doing well!”

The 26-year-old got engaged to Lisa after just a four-month courtship. So what do sis Kelly and mom Sharon think about all of this?

No word yet from papa Ozzy but I’m sure it would go something like this, “Yeumm ugggg ahhh Jack ughummmm yeahhhhhhhh!”

This is especially great news being that it came just after Jack’s celebration of being sober now for 9 years. Congrats to the happy new parents and to Sharon for being one hot granny!

You’ve come a long way Jack (clip contains some Osbourne level wordy-dirds)!
