Jack Osbourne is to become a father for the first time.

The Adrenalin Junkie star has confirmed fiancee Lisa Stelly -- who he got engaged to two weeks ago -- is expecting their first child and he can’t wait to be a dad.

During an appearance on CNN's Piers Morgan Tonight with his parents Ozzy and Sharon Osbourne, he revealed: "My life is absolutely insane right now. 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.”

Jack shot to fame on family reality TV show The Osbournes, but the 25-year-old star has vowed not to put his own offspring through the same experience.

He said: “I'm not going to do a reality show, though!”

Ozzy and Sharon are equally as thrilled by the news, although the heavy metal legend admits he is still in “shock”.

He joked: "I’m in shock. It’s fantastic. It doesn't matter what I think. The baby's on its way."
