Jack Osbourne And Fiancee Lisa Stelly Are Expecting!

Though Jack Osbourne may be in the midst of wedding planning with his fiancee Lisa Stelly, it looks like the pair may need to prepare for another milestone on the way– the arrival of their first child!

After appearing on Piers Morgan Tonight with his family, sans sister Kelly, Jack announced that he and Lisa were expecting.

“My life is absolutely insane right now,” said Jack last night. “I guess technically I do have something to tell you. I’m about to be a father. I’m excited. I’m a little nervous, but I’m excited. It’s going to be fun.”

Though shock rocker and grandpa-to-be Ozzy admitted that he was “in shock” about the “fantastic” news, Jack’s super famous sibling couldn’t contain her excitement and shared her joy via Twitter.

“girls night w/ @lisamarstelly my future sister in law & mother of my niece/nephew we are so happy the news is out so i can talk about it.”

But her love for Lisa, as well as her and Jack’s baby-to-be didn’t stop there!

“been waiting 2 say this for so long im the happiest girl in the world im going to be an auntie! @lisamarstelly welcome to the family i <3 u”

While Jack didn’t say how far along his bride-to-be was in her pregnancy, I’m sure the couple, as well as his family, will continue to share the good news with the world. Even well after they say “I, do.”
